npm-adduser failing on entering npm account's credentials - node.js

Question

I had created an npm package using a different machine. I git cloned that package into a different machine and tried running npm publish and got the following error:
npm ERR! need auth auth and email required for publishing
npm ERR! need auth You need to authorize this machine using `npm adduser`
npm ERR! System Linux 3.13.0-24-generic
npm ERR! command "/usr/bin/nodejs" "/usr/bin/npm" "publish"

npm ERR! code ENEEDAUTH
npm ERR!

I figured I would need to run npm-adduser. So, I ran it and entered my credentials of my npm account. Then I got the following error:
npm http PUT https://registry.npmjs.org/-/user/org.couchdb.user:tarun-dugar
npm http 400 https://registry.npmjs.org/-/user/org.couchdb.user:tarun-dugar

Any idea how I can solve this issue?

The problem was that I was using an old version of npm (1.3.10). To solve this I upgraded npm using the tips from this link: upgrade npm on ubuntu
And finally adding a symlink as described in this link: symlink
