This error usually means Turbopack can’t locate the Next.js package in your project — it’s often related to missing dependencies or an invalid project root.

Try these steps:

1. Make sure next is properly installed in your project:

npm install next react react-dom

2. Check that your package.json includes:

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

3. If you’re running Turbopack manually, make sure you’re inside the project root (where package.json is located).

4. Clear caches and rebuild:

rm -rf .next node_modules
npm install
npm run dev

5. If it still shows the same error, try using the latest Next.js Canary version — this issue happens on some early Turbopack builds:

npm install next@canary

It’s likely a bug in older Turbopack versions that fail to detect the Next.js package correctly. Updating usually fixes it.
