Travis ImportError: No module named 'pep8ext_naming'

[tripleee]

What problem has occurred? What issues has it caused?

A couple of recent builds failed due to what looks like a flake8 module problem on the Travis side (?)

E.g. https://travis-ci.org/Charcoal-SE/SmokeDetector/builds/649816066?utm_source=github_status&utm_medium=notification

What would you like to happen/not happen?

The build should succeed, like it still does on my laptop.

I'm guessing the failed module load is what causes everything after that to go downhill, but I could be wrong.

Actually all builds after this one from yesterday have been failing:

I can't tell if it's significant but one difference seems to be that Travis now downloads and installs Python 3.5 in order to run this test.

The issues we had with Travis CI failing for a day and a half appear to have been that the caches on Travis had become corrupted. The problems stopped when I manually cleared all the caches. If that needs to happen at some point in the future, I found it necessary to log into Travis as SmokeDetector, and delete all the caches on this page.
