title: Does MongoDB node.js driver installation need Python?
body: <p>I am trying to install mongodb driver for Nodejs on Windows 10 and gets the below error about Python.</p>
  
  <p>Is Python a pre-requsite ?
  And that too it expects only Python version 2.5 to 3.0.
  On top of Python it keeps asking for other MS Visual Studio 2008 or MS SDK /  .Net installations ?
  Does it need all these as pre-requsite.</p>
  
  <pre><code>C:\Jay\M101JS&gt;npm install mongodb
