title: How to setup node-gyp behide a proxy
body: <p>When i install karma that use node-gyp to fetch package and do rebuild, and I got a "gyp Error!: connect ECONNERFUSED", THE problem whey node-gyp will connect to internet and my environment is behind corporate proxy, I could download package from npm and I setup npm's proxy already.</p>
