title: python - IO Error [Errno 2] No such file or directory when downloading package
body: <p>I was trying to download a Python wrapper called rawpy on my Windows machine. I used the command "pip install rawpy". I have already looked at many other SO threads but could find no solution. The exact error is :</p>
  
  <blockquote>
    <p>IO Error: [Errno 2] No such file or directory:
    'external/LibRawcmake/CMakeLists.txt'</p>
  </blockquote>
  
  <p>The only dependency for the wrapper is numpy, which I successfully installed. I would like to know how to fix this. Quite new to Python, so any information would help.</p>
