When trying to install the `past` module using pip 10.0.1 using python 3.6.5 I get:
====================================================================
$ pip3 install past --no-compile
Collecting past
  Could not find a version that satisfies the requirement past (from versions: )
No matching distribution found for past
====================================================================

Confirming package exists with pip search:
====================================================================
$ pip3 search past | grep past
past (0.11.1)                                - [Experimental] Run Python 2 code from Python 3
