Comment 5 for bug 1586976

I'm pretty sure it's caused by the improper pip module being installed.

Here is the diff between version which I'm 100% sure was running properly and current tests.

Seems like fixtures 3.0.0 is installed even if specified <2.0.
Another difference is os-testr which is now 0.7.0 and was 0.6.0.

Even pinning those version in the test-requirements.txt causes higher versions to be installed, meaning change was somewhere in other deps.
