I tried the code below, it says Error: Cannot find module 'graceful-fs'
$sudo node-gyp rebuild -g --unsafe-perm
I tried downloading graceful-fs, it still gives the same error.

It is an issue with node permissions, try this:
Back up your computer. On the command line, in your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a
~/.profile
file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.profile
To test your new configuration, install a package globally without using sudo
