Description:

Newer versions of Pip is unable to install packages with Jython as python compiler.
It throws the error:

 File "/home/travis/jython/Lib/site-packages/pip/_vendor/msgpack/fallback.py", line 292, in feed
    self._buffer += view
TypeError: can't concat memoryview to bytearray

You can look here:
https://travis-ci.org/oracc/pyoracc/jobs/368517211

The issue is resolved with pip version of 8.2.1 and less. Check here:
https://travis-ci.org/oracc/pyoracc/jobs/368524652

What I've run:

pip install wheel
pip install setuptools
pip install ply pep8 mako pytest
