title: What are the dependencies for a certain wheel (.whl) package?
body: <p>I would like to install pylab and I don't have a direct access to pip (proxy limitations). I cannot make it through cntlm or other proxy tunneling solutions.</p>
  
  <p>So I have two solutions: </p>
  
  <ol>
  <li><p>install each package manually, run it, install the missing dependency and go back to (1)</p></li>
  <li><p>download the wheel and fetch the dependencies list. </p></li>
  </ol>
  
  <p>I don't know how to do (2). </p>
  
  <p>Is there any easy way to list the required wheel files to install another wheel file?</p>
  
  <p>There are many related questions to "how to use pip offline", but I still did not find happiness there. </p>
