Turbopack Error: Failed to write app endpoint /page

Error message:

Turbopack Error: Failed to write app endpoint /page

This happens because Next.js is not installed correctly - notice it shows Next.js version: 0.0.0. That means the framework files are missing, so Turbopack can’t write the endpoint.
