Installing comtypes 1.1.3-2 but getting 1.1.3 instead
<p>I'm trying to install <code>comtypes</code> using pip. I specified <code>1.1.3.post2</code> as the version number, but pip keeps installing version <code>1.1.3</code> instead.</p>

<p>This is the message I get when trying to install it:</p>

<pre><code>Requested comtypes==1.1.3.post2 from https://pypi.python.org/packages/85/11/722b9ce6725bf8160bd8aca68b1e61bd9db422ab12dae28daa7defab2cdc/comtypes-1.1.3-2.zip#md5=4161cb8bc283a75af85e220ad662d5af,
but installing version None
</code></pre>

<p>I'm baffled. I already tried deleting pip cache directory.</p>
