Bower not getting installed

I am trying to use npm to install bower (with -g or without -g) but unable to do so. The installing wheel just keeps rotating for continuously but nothing gets installed.

I tried looking for help online but nobody seems to have had this issue before.

Solutions tried 1. tried npm cache clean, didn't help. 2. Manually cleared bower folders and lock in the ~/.npm folder.

Node version -- 0.12.0 npm version -- 2.5.1 OS - Yosemite

After a really long wait, I got the following error. My internet is working and neither am I behind a proxy.
