How can I resolve cannot find module npm-cli.js error?

Question

My npm has worked well, however today it shows an error saying,

Error: Cannot find module 'C:\Users\mrsim\node_modules\npm\bin\npm-cli.js'

My npm worked well just an hour ago. I typed "npm start" inside of VSCode to start my react-app and it worked very well!

This nightmare started when I created server folder and typed "npm install express".

Normally when I typed "npm install express" in the terminal, it automatically created node-modules folder and package.json for me without any problem, but none of these appear.

To solve this problem I repair node first, and didn't worked.

Next I changed my environment variable, and didn't worked.

Next I used "SET PATH=C:\Program Files\Nodejs;%PATH%" this sentence in the terminal, and didn't worked.

This is error message appear on terminal. If i go to that directory, i cannot find npm.cli.js

What should I do...?

Answer 1

1. Go to the path that have Appdata\local or Appdata\roaming
2. Delete the npm and npm cache folder in both
3. Get back in terminal, Run npm install again, will see a new path ex: npm notice
4. Run npm install -g [email protected] to update!
5. Install the new path and ready to go

This solved my problems.
