Terminal

`sh: next: command not found`

What it means: You tried to start the app (`npm run dev`), but its packages (`node_modules`) aren't installed in this folder yet.
Likely causes: The project was just cloned or pulled and npm install hasn't run yet.
A previous npm install was interrupted before finishing.
Prevention: Let your agent run npm install whenever you open a project on a new computer or after a pull.

Copy for your agent

Starting the app says `sh: next: command not found`. Run `npm install` first, then start `npm run dev` again.
