title: How to install bson npm package on a Windows 8.1 OS?
body: <p>When trying to <code>npm install -g bson</code> on my Windows 8.1 OS, it fails with the following message:</p>
  
  <p><img src="https://i.stack.imgur.com/zfezQ.png" alt="npm error"></p>
  
  <p>When trying to see what's wrong in the NPM debug log, I've got only that:</p>

  <p>I've tried to search around and all I could find was:</p>
  
  <ul>
  <li>is node and system32 in the PATH ? (yes they are)</li>
  <li>run the command line as administrator (already is)</li>
  <li>is Python and Visual C++ 10 installed ? (yes they are)</li>
  </ul>
  
  <p>And that's it. Does anybody have a clue of what I can do to make this works (the goal here is to install mongoose...) ?</p>
