You're hitting this because Turbopack expects the next package to be installed in your project.

Fix:

Make sure you have Next.js installed:

npm install next

or

yarn add next

If it’s already installed, try deleting node_modules and reinstalling:

rm -rf node_modules .next
npm install

Then re-run your dev server.

Let me know if it still barks after that
