Universal NVM (@jchip/nvm)

A universal node.js version manager for Windows (no admin) and Unix.

Install is simple with a PowerShell script on Windows, or a bash script on Unix.
No admin required on Windows to install or use.
A linked system wide version that can be changed any time.
Change to any version independently in a terminal any time.

Installing Universal NVM on Windows using PowerShell

You don't need admin rights to install or use, only the permission to execute PowerShell scripts.

Tested on Windows 10, 8.1, and 7. Windows 7 requires PowerShell updates, see update instructions.

To install, start a Windows PowerShell and copy and paste one of the scripts below into the shell terminal and press enter.

This will install nvm and current LTS Node.js (v12.13.0) to directory nvm under your home specified by $Env:USERPROFILE.
If you want to install this under another directory, then set it with the param -nvmhome.
If you don't set it, then $Env:NVM_HOME will be checked, and if non-existent, then a Directory Browser dialog will be opened for you to create and choose a directory.

You can retrieve the install script from multiple sources. Listed below are three options for you to choose from in case one of them is down.

Installing from github.com

Retrieve install script from github.com directly:

cd $Env:USERPROFILE;
Invoke-WebRequest https://raw.githubusercontent.com/jchip/nvm/v1.9.0/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1

Installing from unpkg.com

Retrieve install script from unpkg.com:

cd $Env:USERPROFILE;
Invoke-WebRequest https://unpkg.com/@jchip/nvm@1.9.0/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1

Installing from jsdelivr.net

Retrieve install script from jsdelivr.net:

cd $Env:USERPROFILE;
Invoke-WebRequest https://cdn.jsdelivr.net/npm/@jchip/nvm@1.9.0/install.ps1 -OutFile install.ps1;
.\install.ps1 -nvmhome $Env:USERPROFILE\nvm;
del install.ps1

Windows 7 Updates

PowerShell version 4+ is required.

For Windows 7, you can update it to version 5.1 with the following instructions:

Go to https://www.microsoft.com/en-us/download/details.aspx?id=54616
Click Red Download button
Download Win7AndW2K8R2-KB3191566-x64.zip or Win7-KB3191566-x86.zip for 32-bit
Unzip the file
Run the package Win7AndW2K8R2-KB3191566-x64.msu or Win7-KB3191566-x86.msu for 32-bit

After it's completed and rebooted, launch PowerShell and type $PSVersionTable to check.

PSVersion should be something like 5.1.#####.####

Troubleshooting

Running scripts disabled

If you get the error:

install.ps1 cannot be loaded because running scripts is disabled on this system.

Then you need to set execution policy for PowerShell to RemoteSigned with the command:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

See this StackOverflow question for details.

You need to keep this policy if you want to use nvm in PowerShell to switch node.js versions.

No PowerShell - Manual Install

If for some reason you absolutely can't have PowerShell or permission to install from it, then you can try to manually install following these steps:

Download the package zip file from https://github.com/jchip/nvm/archive/v1.9.0/.zip
1. Extract this file to your home directory. You will get a new directory nvm-1.9.0.
2. Rename it to nvm, for example: C:\Users\<username>\nvm
Download the zipfile https://nodejs.org/dist/v20.12.1/node-v20.12.1-win-x64.zip
1. Extract this file to C:\Users\<username>\nvm. You will get a new directory node-v20.12.1-win-x64
2. Move node.exe from that directory into C:\Users\<username>\nvm
3. (optional) You can delete the directory after if you want.
Open RegEdit.exe, in HKEY_CURRENT_USER/Environment
1. Add the following entries
  1. NVM_HOME -> C:\Users\<username>\nvm
  2. NVM_LINK -> C:\Users\<username>\nvm\nodejs\bin
2. Append the following to the entry Path
  1. ;C:\Users\<username>\nvm\bin;C:\users\<username>\nvm\nodejs\bin
Open Command Prompt, and run nvm install lts, note the version installed, and then nvm link <version>.

Make sure to replace <username> above with your actual user name.

Using Git Bash on Windows

If you want to use Universal NVM with Git Bash after installing on Windows via PowerShell:

First install nvm using PowerShell (see instructions above)
Open Git Bash
Run the setup script:
```
$NVM_HOME/bin/nvm-setup.sh
```
Restart Git Bash or run:
```
source ~/.bashrc
```

Now you can use nvm commands in Git Bash just like on Unix systems.

Using PowerShell 7 on macOS/Linux

Universal NVM supports PowerShell 7 (pwsh) on macOS and Linux. If you have PowerShell 7 installed, you can use the PowerShell scripts directly on Unix systems.

Installing PowerShell 7:

On macOS (using Homebrew):

brew install --cask powershell

On Linux, follow the official PowerShell installation guide.

Using nvm in PowerShell on macOS/Linux:

After installing Universal NVM (via bash/zsh), you can use the PowerShell scripts:

# Set up NVM_HOME
$Env:NVM_HOME = "$HOME/nvm"

# Add nvm function to your PowerShell profile
function nvm {
    & "$Env:NVM_HOME/bin/nvm.ps1" @args
}

# Use nvm commands
nvm --version
nvm ls
nvm install lts
nvm use 20

Enable auto-use in PowerShell:

PowerShell on macOS/Linux supports the same auto-use functionality as Windows:

# Enable auto-use (adds to $PROFILE)
nvm auto-use enable

# Enable with cd wrapper mode (recommended)
nvm auto-use enable --cd

# Reload your profile
. $PROFILE

The auto-use setup will automatically detect that you're on Unix and configure the correct paths (using forward slashes instead of backslashes).

Adding to PowerShell Profile:

To make nvm available in every PowerShell session, add the following to your PowerShell profile ($PROFILE):

# Set up Universal NVM for PowerShell on macOS/Linux
$Env:NVM_HOME = "$HOME/nvm"
$Env:PATH = "$Env:NVM_HOME/bin:$Env:PATH"

function nvm {
    & "$Env:NVM_HOME/bin/nvm.ps1" @args
}

To find your profile location: $PROFILE (typically ~/.config/powershell/Microsoft.PowerShell_profile.ps1 on Unix)

To create it if it doesn't exist:

New-Item -Path $PROFILE -ItemType File -Force

Installing Universal NVM on Unix

Because this is implemented in node.js, it happens to work on Unix also. It just need a different install script using bash.

To retrieve and run the install script, provided below are three options for you to choose from in case one of them is down.

Please pick one and then copy and paste it into a bash terminal to run.

Installing from github.com

Retrieve the install script from github.com:

Using cURL and the install script:

export NVM_HOME=~/nvm; curl -o- https://raw.githubusercontent.com/jchip/nvm/v1.9.0/install.sh | bash

or wget:

export NVM_HOME=~/nvm; wget -qO- https://raw.githubusercontent.com/jchip/nvm/v1.9.0/install.sh | bash

Installing from unpkg.com

Retrieve the install script from unpkg.com:

Using cURL and the install script:

export NVM_HOME=~/nvm; curl -o- https://unpkg.com/@jchip/[email protected]/install.sh | bash

or wget:

export NVM_HOME=~/nvm; wget -qO- https://unpkg.com/@jchip/[email protected]/install.sh | bash

Installing from jsdelivr.net

Retrieve the install script from jsdelivr.net:

Using cURL and the install script:

export NVM_HOME=~/nvm; curl -o- https://cdn.jsdelivr.net/npm/@jchip/[email protected]/install.sh | bash

or wget:

export NVM_HOME=~/nvm; wget -qO- https://cdn.jsdelivr.net/npm/@jchip/[email protected]/install.sh | bash

Shell Initialization on Unix

The Universal NVM installation automatically updates your shell profile files to initialize nvm. The behavior differs between zsh and bash:

Zsh (macOS default)

For zsh users, the installer updates both .zshenv and .zshrc:

.zshenv: Sourced for ALL shells (interactive and non-interactive)
.zshrc: Sourced for interactive shells only

This means:

✅ Terminal sessions have nvm available
✅ Non-interactive scripts have nvm available
✅ GUI applications (like VS Code) have nvm available (when combined with nvx --install-to-user)

Bash

For bash users, the installer updates .bashrc or .bash_profile:

.bash_profile: Sourced for login shells (macOS default)
.bashrc: Sourced for interactive non-login shells (Linux default)
Non-interactive shells: NOT sourced by default

This means:

✅ Terminal sessions have nvm available
❌ Non-interactive bash scripts do NOT have nvm by default

Using nvm in bash scripts:

If you need nvm in a bash script, you have three options:

Source the profile explicitly in your script:

#!/bin/bash
source ~/.bashrc
node --version

Use a login shell with the shebang:
```
#!/bin/bash -l
node --version
```
Set BASH_ENV to automatically source a file for non-interactive shells:
```
export BASH_ENV=~/.bashrc
```
You can add this to your .bash_profile to make it permanent, but be aware this will affect all bash scripts system-wide.

Note: This is standard bash behavior by design - non-interactive shells have a minimal environment for performance and predictability.

Auto-Use: Automatic Version Switching

Universal NVM can automatically switch Node.js versions when you change directories. When enabled, it will check for .nvmrc, .node-version, or package.json files and automatically switch to the specified version.

Quick Start:

# Enable automatic switching (modifies your shell profile)
nvm auto-use enable

# Enable with cd wrapper mode (more efficient, recommended)
nvm auto-use enable --cd

# Disable automatic switching
nvm auto-use disable

# Manually switch to version specified in current directory
nvm auto-use

Two modes available:

Auto-use offers two different modes for triggering version switches:

Prompt-based mode (default) - Runs on every prompt
- ✅ Catches ALL directory changes (cd, pushd, GUI navigation, terminal opening)
- ⚠️ Slightly more overhead (runs every time you press Enter)
- Best for: Ensuring you never miss a version switch
cd wrapper mode (--cd flag) - Runs only on cd commands
- ✅ More efficient (only runs when you actually change directories)
- ✅ Cleaner (direct cause and effect)
- ⚠️ Misses directory changes from pushd, popd, or terminal opening in new location
- Best for: Performance-conscious users who primarily use cd

Which mode to choose:

# Use prompt-based if you want comprehensive coverage
nvm auto-use enable

# Use cd wrapper if you prefer efficiency
nvm auto-use enable --cd

Note for Zsh users: Zsh always uses the optimal chpwd_functions mechanism (triggers only on actual directory change), so the --cd flag has no effect. Zsh users automatically get the best of both worlds!

What nvm auto-use enable does:

Bash/Zsh: Adds auto-use setup to ~/.bashrc, ~/.bash_profile, or ~/.zshrc
PowerShell: Adds auto-use setup to your PowerShell profile ($PROFILE)
Automatically detects your shell and modifies the correct profile file

After enabling, restart your terminal or source your profile:

source ~/.bashrc       # Bash on Linux
source ~/.bash_profile # Bash on macOS
source ~/.zshrc        # Zsh
. $PROFILE             # PowerShell

How it works:

When you change directories, auto-use checks for version files (.nvmrc, .node-version, or package.json)
If found and a different version is needed, it switches and shows: Using node v20.10.0 (auto-use from .nvmrc)
If the version is already active, it does nothing (fast and silent!)
If the version isn't installed, it shows an error once per shell session: Version 16.0.0 from .nvmrc not installed
- The error is only shown once - subsequent cd commands won't repeat the same error
- This helps you know which version to install without spamming your terminal
If no version file is found, it does nothing (no error messages)

Manual vs Automatic invocation:

Automatic (via cd/prompt hooks): Uses --silent flag to suppress "no version file found" errors
Manual (typing nvm auto-use): Shows all messages including "no version file found" errors

When auto-use is triggered automatically by changing directories, you'll see:

✓ Version switch messages (always shown)
✓ "Version not installed" errors (shown once per shell session)
✗ "No version file found" errors (suppressed)

Version Files (.nvmrc, .node-version, and package.json)

When you run nvm use or nvm auto-use without specifying a version, Universal NVM will automatically look for a version specification in the current directory.

Supported sources (in priority order):

.nvmrc - nvm-specific version file (checked first)
.node-version - Universal Node.js version file (checked if .nvmrc not found)
package.json → engines.node - Fallback to package.json engines field (checked if no version files exist)

Usage:

# Option 1: Create a .nvmrc file
echo "20.10.0" > .nvmrc

# Option 2: Create a .node-version file
echo "20.10.0" > .node-version

# Option 3: Use package.json engines.node
cat > package.json << EOF
{
  "name": "my-project",
  "engines": {
    "node": ">=18.0.0"
  }
}
EOF

# Use the version specified in any of these sources
nvm use
# Output varies based on source:
# - Read version 20.10.0 from .nvmrc
# - Read version 20.10.0 from .node-version
# - Read node requirement ">=18.0.0" from package.json
#   Found installed version v20.10.0 matching ">=18.0.0"

File format:

.nvmrc and .node-version files should contain a plain text version number on a single line:

20.10.0

Or with the v prefix:

v20.10.0

Semver ranges:

All version sources support semantic versioning (semver) ranges. Universal NVM will automatically select the highest installed version that satisfies the requirement.

In .nvmrc or .node-version:

>=18.0.0

^20.0.0

In package.json engines.node:

The engines.node field supports the same semver syntax:

{
  "engines": {
    "node": ">=18.0.0"        // Any version 18 or higher
  }
}

{
  "engines": {
    "node": "^20.0.0"         // Latest 20.x version
  }
}

{
  "engines": {
    "node": ">=18.0.0 <21.0.0"  // Version 18 or 20, but not 21+
  }
}

If no installed version matches a semver range, you'll see a helpful error message suggesting which version to install.

Priority when multiple sources exist:

If multiple version sources exist in the same directory, Universal NVM will prefer them in this order:

# With all three present
$ cat .nvmrc
18.20.0

$ cat .node-version
20.10.0

$ cat package.json
{
  "engines": { "node": ">=16.0.0" }
}

$ nvm use
# Output: Read version 18.20.0 from .nvmrc
# .node-version and package.json are ignored

Benefits of each approach:

.nvmrc - Best for teams using traditional nvm:

Standard for nvm users
Supports both exact versions and semver ranges
Most familiar to developers using nvm

.node-version - Best for cross-tool compatibility:

Universal standard for Node.js version specification
Supports both exact versions and semver ranges
Makes your project more portable

package.json engines.node - Best for existing projects:

Already part of Node.js ecosystem
Supports semver ranges for flexibility
Single source of truth (no separate version file needed)
Automatically used as fallback if no .nvmrc or .node-version exists

Environments

These env flags can be set:

name	values	description
`NVM_PROXY`	string	An URL to a network proxy (highest priority)
`https_proxy`	string	An URL to a network proxy for HTTPS (lowercase, npm convention)
`HTTPS_PROXY`	string	An URL to a network proxy for HTTPS (uppercase)
`http_proxy`	string	An URL to a network proxy for HTTP (lowercase, npm convention)
`HTTP_PROXY`	string	An URL to a network proxy for HTTP (uppercase)
`NVM_VERIFY_SSL`	`true`/`false`	Controls SSL certificate verification (default: `true`)
`NVM_COREPACK_ENABLED`	`true`/`false`	Enable corepack after installation (default: `false`)

Proxy Priority:

Command-line -p flag (highest priority)
NVM_PROXY (overrides all protocol-specific proxies)
Protocol-specific proxy (matches URL being fetched):
- For HTTPS URLs: https_proxy → HTTPS_PROXY → http_proxy → HTTP_PROXY
- For HTTP URLs: http_proxy → HTTP_PROXY

Following npm convention, lowercase environment variables are checked first, then uppercase.

SSL Certificate Verification (`NVM_VERIFY_SSL`)

By default, Universal NVM verifies SSL/TLS certificates when downloading Node.js from distribution servers. This ensures you're downloading from a trusted source.

When to disable SSL verification:

You may need to set NVM_VERIFY_SSL=false in these scenarios:

Corporate proxies with SSL inspection - Your company's network intercepts HTTPS connections with self-signed certificates
Internal mirrors - You're using an internal Node.js mirror with self-signed certificates
Development environments - Testing with local servers using self-signed certificates

How to use:

# Disable SSL verification via environment variable (Unix/macOS)
export NVM_VERIFY_SSL=false
nvm install lts

# Disable SSL verification via environment variable (Windows PowerShell)
$Env:NVM_VERIFY_SSL = "false"
nvm install lts

# Disable SSL verification via command-line flag
nvm install lts --no-ssl

Security Warning: Disabling SSL verification makes you vulnerable to man-in-the-middle attacks. Only disable it when you trust your network and understand the risks. Re-enable verification after completing your task:

# Re-enable SSL verification (Unix/macOS)
export NVM_VERIFY_SSL=true

# Re-enable SSL verification (Windows PowerShell)
$Env:NVM_VERIFY_SSL = "true"

Corepack Support (`NVM_COREPACK_ENABLED`)

Corepack is a built-in Node.js feature (available since v16.9.0) that manages package managers like Yarn and pnpm. It allows you to use the exact package manager version specified in your project's package.json without manually installing them.

When to enable corepack:

Using Yarn or pnpm - Your project uses Yarn or pnpm instead of npm
Version consistency - You want to ensure everyone on your team uses the same package manager version
Modern projects - You're working with projects that specify packageManager in package.json

How to use:

# Enable corepack via environment variable (Unix/macOS)
export NVM_COREPACK_ENABLED=true
nvm install lts

# Enable corepack via environment variable (Windows PowerShell)
$Env:NVM_COREPACK_ENABLED = "true"
nvm install lts

# Enable corepack via command-line flag (one-time)
nvm install 20 --corepack

# Disable corepack for a specific installation
nvm install 18 --no-corepack

What corepack does:

After installing Node.js, Universal NVM will automatically run corepack enable, which:

Makes yarn and pnpm commands available
Respects the packageManager field in your package.json
Automatically uses the correct package manager version for your project

Example package.json with packageManager:

{
  "name": "my-project",
  "packageManager": "[email protected]",
  "dependencies": {
    "express": "^4.18.0"
  }
}

With corepack enabled, running pnpm install will automatically use pnpm version 9.1.0, even if you don't have it installed globally.

Note: If corepack fails to enable (e.g., on Node.js versions before v16.9.0), Universal NVM will show a warning but will not fail the installation. You can manually enable it later with:

corepack enable

Priority: --corepack flag > NVM_COREPACK_ENABLED env var > default (false)

nvx - Execute with local node_modules

The nvx command allows you to run commands from your local node_modules/.bin directory without needing to specify the full path. It only runs locally installed packages, making it fast and predictable for running project-specific tools.

Basic Usage

# Run eslint from local node_modules
nvx eslint src/

# Run prettier from local node_modules
nvx prettier --write .

# Run any locally installed CLI tool
nvx jest --watch

Show Help

nvx --help
# or
nvx -h

Installing to PATH (macOS/Linux only)

On macOS and Linux, you can optionally add the Universal NVM bin directory to your system PATH to make nvm commands available in GUI applications (like VS Code).

Install to User PATH (recommended)

This adds Universal NVM to your user's PATH. Works with GUI applications and doesn't require sudo:

macOS:

nvx --install-to-user
# Log out and log back in for changes to take effect

Linux:

nvx --install-to-user
# Log out and log back in for changes to take effect

Install to System PATH (all users)

This adds Universal NVM to the system-wide PATH for all users. Requires sudo:

macOS:

sudo nvx --install-to-system
# Restart your terminal for changes to take effect

Linux:

sudo nvx --install-to-system
# Log out and log back in for changes to take effect

Note for Windows users: On Windows, the installation script automatically adds both %NVM_HOME%\bin and %NVM_LINK% to your user PATH in the Windows registry. This makes Universal NVM, node, and npm immediately available to all applications (terminal, GUI apps like VS Code, etc.) without needing to run any additional commands. The nvx --install-to-user and nvx --install-to-system commands are therefore not needed on Windows.

How it Works

The nvx --install-to-user command uses platform-specific mechanisms to make Universal NVM available to GUI applications:

macOS:

Creates a LaunchAgent at ~/Library/LaunchAgents/com.jchip.universal-nvm.plist that runs at login to set environment variables for the user session. This makes Universal NVM available to:

All GUI applications (VS Code, editors, etc.)
Terminal windows
Background processes

The LaunchAgent adds both paths to your environment:

~/nvm/bin - nvm commands (nvm, nvx)
~/nvm/nodejs/bin - Node.js executables (node, npm) - only available after running nvm link <version>

Linux:

Creates a systemd user environment file at ~/.config/environment.d/10-jchip-universal-nvm.conf. This file is read by systemd-based desktop environments at login and makes Universal NVM available to:

All GUI applications launched from the desktop
Applications started by systemd user services
Any process in your user session

The environment file adds both paths:

~/nvm/bin - nvm commands (nvm, nvx)
~/nvm/nodejs/bin - Node.js executables (node, npm) - only available after running nvm link <version>

Important: The ~/nvm/nodejs/bin directory is a symlink created by nvm link <version> that points to the default Node.js version. You must run nvm link to set up a default Node.js version before GUI applications can access node and npm. The install script does this automatically.

Note: On Linux systems not using systemd, this feature may not work. In that case, you can manually add the paths to your ~/.profile or consult your distribution's documentation for setting user environment variables.
