How to restore deleted 'node_modules' folder?

Question

On Ubuntu 16.04 I accidently deleted the 'node_modules' folder so that I can't run npm anymore. I get the error:

bash: /usr/local/bin/npm: No such file or directory.

How can I fix this?

Answer 1

If package.json is present in your project directory, which usually is, then run npm install and all the packages will be restored as well as the node_modules directory, where they are stored.
