title: doesn't setup.py develop use wheel for install_requires?
body: <p>I have the impression that (using setuptools):</p>
  
  <pre><code>python setup.py develop
  </code></pre>
  
  <p>Won't use wheels when installing required packages (specified in install_requires).</p>
  
  <p>Questions:</p>
  
  <ol>
  <li>is my impression correct?</li>
  <li>is there a way to force it to use wheel?</li>
  </ol>
  
  <p>I am talking about <a href="https://github.com/ninuxorg/nodeshot/blob/master/setup.py" rel="noreferrer">this particular setup script</a>.</p>
