Comment 3 for bug 1649693

Max, your original comment here says:

"flake8 3.2.1 (pyflakes: 1.3.0, flake8-comprehensions: 1.2.1, mccabe: 0.5.2, pycodestyle: 2.2.0) CPython 2.6.6 on Linux"

So yes, you did install it on Python 2.6.6. You need to do `python2.7 -m pip install flake8` to get it to install on 2.7 for you (it would appear).
