npm 命令不起作用

Question

I have installed Node.js and at first when I wrote an npm command like npm install -g <> or npm start it worked, but now it doesn't. I removed and installed node again and am still facing the same problem:

~$ npm install
~$

No action is made and the terminal returns back to normal.

npm install looks for a package.json file in your current directory. It installs all the dependencies listed in the package.json . Similarly npm start looks in the package.json scripts to see what command it should really run. If it doesn't work now, you are probably in the wrong directory. If you are in the correct directory, can you provide more information like the exact error message you are getting?
