pep8 has been renamed to pycodestyle (GitHub issue #466)
Use of the pep8 tool will be removed in a future release.
Please install and use `pycodestyle` instead.
Thanks for spotting this. I just pushed a slightly different fix that updates the test dependencies in setup.py and uses those, so I'm going to close this.
