NPM installation issues on Mac OS Mavericks

Question

I am trying to get to grips with AngularJS, NodeJS and Ruby on Rails. When trying to install npm packages like yeoman, grunt etc. I receive an error in my Terminal which I have listed below:

npm ERR! Error: EACCES, open '/Users/Jabane/.npm/glob/3.2.11/package/package.json.25961'

npm ERR!  { [Error: EACCES, open '/Users/Jabane/.npm/glob/3.2.11/package/package.json.25961']

npm ERR!   errno: 3,

npm ERR!   code: 'EACCES',

npm ERR!   path: '/Users/Jabane/.npm/glob/3.2.11/package/package.json.25961',

npm ERR!   parent: 'browserify' }

npm ERR!

npm ERR! stack Error: EACCES, open '/Users/Jabane/.npm/glob/3.2.11/package/package.json.25961'

npm ERR! 

npm ERR! Additional logging details can be found in:

What might be the issue in this case? Your assistance is highly appreciated.

Thanks

This is a permissions issue. You need to prefix your npm install command with sudo, e.g.:

sudo npm install yeoman

It will prompt you for your User Account's password; and subject to the correct password being provided, will then install the packages correctly.
