make test fails on a clean install

[aarchiba]

When I try to run make test on a clean install, I get an error out of flake8:

flake8 .

I don't know whether this is a misconfiguration or what, but all I did was install enterprise from conda (for the dependencies), then pip install -e . so I could work on the code, then make test.

I am using flake8 version 6.0.0.

This particular error arises because .flake8 has comments on the same lines as ignore arguments; comments are only allowed on separate lines.

Once this is fixed, flake8 . still fails:
