title: Cannot install node-sass
body: <p>I'm in an environment where I am required to run a local proxy, and I am unable to install node-sass. When I try the following:</p>
  
  <pre><code>npm install -g node-sass
  </code></pre>
  
  <p>I get an error:</p>
  
  <blockquote>
    <p>Cannot download "<a href="https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-48_binding.node" rel="nofollow noreferrer">https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-48_binding.node</a>": tunneling socket could not be established, cause=read ECONNRESET</p>
  </blockquote>
  
  <p>I have already installed cntlm and configured it correctly. To verify I use the porxy server to access internet and it works fine.</p>
  
  <p>The following environment variables are set</p>
  
  <pre><code>http_proxy  -&gt;  http://localhost:3128
  https_proxy -&gt;  http://localhost:3128
  </code></pre>
  
  <p>Have also added the following to my .npmrc</p>
  
  <pre><code>https-proxy=http://localhost:3128
  http-proxy=http://localhost:3128
  proxy=http://localhost:3128
  </code></pre>
  
  <p>Also tried by adding slashes to the end but the result is the same. </p>
  
  <p>Any clues and help would be appreciated since I have no idea how to resolve this.</p>
  
  <p>Additional details:</p>
  
  <pre><code>node -v 
  v6.11.4
  
  npm -v
  5.5.1
  </code></pre>
