title: Is this possible to install node-sass offline proxy
body: <p>I'm trying to install node-sass module using npm but each time an error displayed about a problem in network configuration that's because i'm using proxy and private registry this is the error : </p>
  
  <pre><code>This is most likely not a problem with node-gyp or the package itself and is related to network connectivity In most cases you are behind a proxy or have bad network setting 
  </code></pre>
