OS X Uninstall a distutils installed project
<p>I'm on El Capitan and I want to install numpy with pip. However I get the following error:</p>

<pre><code>Detected a distutils installed project ('numpy') which we cannot uninstall. The metadata provided by distutils does not contain a list of files which have been installed, so pip does not know which files to uninstall.
</code></pre>

<p>The existing numpy version seems to be 1.10.4 and the one I try to install is 1.9.2, but I need it. Is there a way to uninstall this version with distutils? Or at least any way to tell pip that there is numpy installed?</p>
