How to install anything using npm install under a proxy
<p>I'm trying to use the following tutorial to learn ReactJS: <a href="http://www.tutorialspoint.com/reactjs/reactjs_environment_setup.htm" rel="nofollow">http://www.tutorialspoint.com/reactjs/reactjs_environment_setup.htm</a></p>

<p>I'm on a corporate network, so I'm under a proxy, hence I cannot install anything using npm install.. I need to do the following: <code>npm install -g babel; npm install -g babel-cli; npm install webpack --save; npm install webpack-dev-server --save; npm install react --save</code> etc.. So, how do I do that under a proxy?</p>
