title: Fail to install PyX using Anaconda
body: <p>I'm having problems installing python modules PyX, I received the following error when using pip:</p>
  
  <pre><code>$ pip install PyX
  Collecting PyX
    Could not find a version that satisfies the requirement PyX (from versions: )
    Some externally hosted files were ignored as access to them may be unreliable (use --allow-external PyX to allow).
  No matching distribution found for PyX
  </code></pre>
  
  <p>Then I tried conda install, but it cannot locate it. I also searched and found nothing. Then I tried pip allow external - doesn't work on either Cygwin or cmd:</p>
  
  <pre><code>$ pip install --allow-external pyx pyx
  Collecting pyx
    Downloading https://downloads.sourceforge.net/project/pyx/pyx/0.14/PyX 0.14.tar.gz (2.5MB)
  No files/directories in c:\cygwin\tmp\pip-build-vqqlqz\pyx\pip-egg-info (from PKG-INFO)
  </code></pre>
  
  <p>I've never seen such error before. Anyone here has some suggestion please (installed under Anaconda preferred)? Thank you very much in advance.</p>
