title: pip to chose packages from a private index over PyPi even on name conflicts?
body: <p>I have set up a <a href="https://www.devpi.net/" rel="nofollow noreferrer">devpi</a> server to host my own Python modules. I would like to use pip to install them and for pip to <em>install in preference my modules, not those in PyPi</em>.</p>
  
  <p>So far, I have this:</p>
  
  <pre><code>[global]
  timeout = 60
  index-url = http://devpi.example.org/root/public/+simple/
  trusted-host = devpi.example.org
  extra-index-url = http://devpi.example.org/root/pypi/+simple/
  </code></pre>
  
  <p>Which works fine as long as there is no name conflict. If there is, the highest version wins which is not what I want.</p>
  
  <p>I really do not wish to register empty projects on PyPi just to have the names reserved.</p>
  
  <p><em>Is there any way to get what I want?</em></p>
