How to fix npm „Cannot find module ‚graceful-fs'“ error

Problem:

When running any npm command, you get a stacktrace similar to the following:

Error: Cannot find module 'graceful-fs'
at Function.Module._resolveFilename (module.js:338:15)
at Function.Module._load (module.js:280:25)
at Module.require (module.js:362:17)
at require (module.js:378:17)
at Object.<anonymous> (/usr/share/npm/lib/utils/ini.js:32:10)
   at Module._compile (module.js:449:26)
at Object.Module._extensions..js (module.js:467:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Module.require (module.js:362:17)

Solution:

Your npm isn’t properly installed. Run

curl https://npmjs.org/install.sh | sudo bash

This reinstalls npm on your computer, the issue should be resolved afterwards.

You might need to restart your shell after that for the changes to take effect.

In some cases even the installer fails because of the graceful-fs error. In this case you might need to remove npm using your distribution’s package manager first, e.g.

sudo apt-get remove npm

After this, try installing npm again as shown above.
