title: jsdom.env not working on node.js C9
body: <p>So I've been working with Node.js on C9 recently and ran into this problem in a javascript file:</p>
  
  <pre><code>jsdom.env("", function(err, window) {
  TypeError: jsdom.env is not a function
  </code></pre>
  
  <p>Here is my code:</p>
  
  <pre><code>var jsdom = require('jsdom');
  var $;
  jsdom.env("", function(err, window) {
  console.log("what");
  if (err) {
      console.error(err);
      return;
  }
  
  $ = require("jquery")(window);
  
  $.ajax(settings).done(function (response) {
       console.log(response);
    });
  });
  </code></pre>
  
  <p>I updated all my dependencies as well as Node itself but still get this problem. Does anyone know what's up? </p>
