Sveltekit / Build step: "PrismaClient" is not exported by "../../packages/database/generated/prisma/index.js" #27109
Description
Bug description
I have followed the How to use Prisma ORM with Turborepo guide.
All is working fine in dev mode, and npm run check does not report any error.
But, npm run build report this:
error during build:
../../packages/database/src/connect.ts (5:9): "PrismaClient" is not exported by "../../packages/database/generated/prisma/index.js", imported by "../../packages/database/src/client.ts".
Location:
import { PrismaClient } from "../generated/prisma"
^
at getRollupError (...)
All works fine if I choose the old "generate in node_modules" pattern.
Thank you.
Severity
🚨 Critical: Data loss, app crash, security issue
Reproduction
Expected vs. Actual Behavior
No rollup error.
Frequency
Consistently reproducible
Does this occur in development or production?
Only in production (e.g., query engine, generated client)
Is this a regression?
Works without "output" in generator client.
Workaround
Do not use "output" in generator client.
