This suggests that Turbopack can’t locate the next package in your project. This usually means it wasn’t properly installed or your project isn’t structured as expected.

Try running:

npm install next react react-dom
# or
yarn add next react react-dom

And checking package.json:

"dependencies": {
  "next": "^15.3.5",
  "react": "^18.2.0",
  "react-dom": "^18.2.0"
}

If that doesn't fix it. Let's do a hard reset.
In the root of your project run the following:

rm -rf node_modules .turbo .next package-lock.json yarn.lock
npm install

Once installed, try run your development server

npm run dev
