title: error while installing npm canvas
body: <p>I'm trying to use this repository:
  <a href="https://github.com/lokesh/color-thief/" rel="nofollow">https://github.com/lokesh/color-thief/</a></p>
  
  <p>While trying to use it I realized I needed to install the <strong>npm canvas</strong> package.
  I went to <a href="https://www.npmjs.com/package/canvas" rel="nofollow">https://www.npmjs.com/package/canvas</a>, but that didn't work so I went to the Installation Wiki at <a href="https://github.com/Automattic/node-canvas/wiki/Installation---Windows" rel="nofollow">https://github.com/Automattic/node-canvas/wiki/Installation---Windows</a>.</p>
  
  <p>I've installed Python 2.7, the Express Visual Studio package, and GTK 2 as written in the instructions. I also ran <code>npm install -g node-gyp</code> in the cmd and it seemed to go through with no errors.</p>
  
  <p>When after all this I try to run <code>npm install canvas</code> I still get errors. I'm attaching the npm-debug.log here:</p>
