Setup npm

If you want to use global path with npm, not local.

1. Install npm 2. `npm install -g {modules}` - Sometimes it gets permission error

-> Comfirm path with `npm -g list`
-> change the permission of the directory 

WARNING: If the displayed path is just /usr, switch to Option 2 or you will mess up your permissions.
-> sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

1. try to run the module
   {module} --version

   • when it gets an error {module} command not found

   try to run:
   export PATH=(npm config get prefix)/{lib/node_modules,bin,share}:$PATH > ~/.profile
source ~/.profile
   Make sure there is a path in .profile

It will work.
