I need help please! about glitch

can you help me? i have a problem
when i try npm in the terminal he answers me: -su: npm: command not found
and when i try pnpm: /usr/bin/env: ‘node’: No such file or directory
pls…i don’t want to lose this project…because is private…

it looks like glitch thinks your project is a static project. you should be able to fix that up by making a package.json file and then reloading the terminal
