Well, nice work on all of the troubleshooting. The previous screenshot I
posted was from a separate virtual environment that was created from a
separate 2.7.13 installation of Python, though I do have 2.7.6 installed
globally. You can see how the installation was created with this script
https://gist.github.com/mradamcox/e66f5008a72c1896003ecc785cb643fe. The
idea was to make an installation completely agnostic of whatever python
already exists on a windows operating system.
Anyway, again, thanks for figuring this out. For now, I'll change the
documentation to recommend that 2.7.12 be used in favor of 2.7.13.
