Next.js version: 0.0.0

Error message:

Turbopack Error: Next.js package not found

I think Turbopack can’t resolve next in your app. The log shows “Next.js version: 0.0.0 / Next.js package not found”, which means there’s no next package in the app’s node_modules (often happens in monorepos or after a broken install)

hmm try ( pick 1 your tool)
npm
#bash
rm -rf node_modules package-lock.json .next
npm i next@latest react@latest react-dom@latest
npm run dev

yarn
#bash
rm -rf node_modules .next
yarn add next react react-dom
yarn dev

pnpm (monorepo tip)
#bash
run from the APP package, not the workspace root
pnpm add next react react-dom --filter ./apps/
pnpm -C ./apps/ dev

Make sure apps//package.json has:

"dependencies": { "next": "...", "react": "...", "react-dom": "..." }

Also check

You’re running dev from the app folder that has package.json (not the parent).

No lockfile mismatch (delete and reinstall as above).

If it still fails, run npx next info and share the output + your package.json to confirm next is properly listed.

This error goes away as soon as the app can resolve a real next version (e.g., 14/15) in its dependencies.

아니요 그 문제가 아닙니다. 저의 개발환경은 yarn berry pnp 기능을 이용하고있으면 package.json script에 next dev --turbopack 또는 next build --turbopack 이것을 하면 제가 겪은 에러가 발생합니다 하지만 --turbopack 을 제거하면 되긴하지만 turbopack을 사용하면서 pnp 기능을 사용할 수는 없는걸까요 ?

Turbopack doesn’t support Yarn Berry PnP yet. With PnP there’s no node_modules/, so Turbopack can’t resolve next → it shows Next.js version: 0.0.0.

Workarounds (pick one):

Use node_modules linker for this app:

yarnrc.yml
nodeLinker: node-modules

yarn install
yarn next dev --turbopack

Keep PnP, use Webpack (drop Turbopack):

yarn next dev
or
yarn next build

(Sometimes works) Unplug the packages so they’re materialized on disk:

yarn unplug next react react-dom
yarn next dev --turbopack
