Problem was with Firewall in my Network Connection.
Due to security policy command C:\wamp\www\nodetutorial>npm install socket.io
was not getting any response when it was trying to
npm http GET https://registry.npmjs.org/socket.io
when I tried the same command at my home without any firewall it worked fine..I got no error
