title: How to get yarn install --offline with node-sass working?
body: <p>I am trying to use <code>yarn</code> in offline mode because the build server I am using does not have access to <code>yarn</code> registry or <code>github.com</code>.</p>
  
  <p>I found this <a href="https://yarnpkg.com/blog/2016/11/24/offline-mirror/" rel="noreferrer">article</a> on how to use <code>yarn</code> in offline mode which works great until I added node-sass. </p>
  
  <p>It appears even if you use <code>yarn install --offline</code>, <code>node-sass</code> will go to <code>github.com</code> to download <code>libsass</code>.</p>
  
  <p>Is there a way to instruct <code>node-sass</code> to use an offline version of <code>libsass</code> instead of going to <code>github.com</code>?</p>
