AttributeError on pytest

[tdevilleduc]

OS: Win10
Python: 3.7.5 But it's the same for 3.7.7

I'm facing a problem when I try to execute pytest

λ python --version
Python 3.7.5

λ pip --version
pip 20.0.2 from c:\users\devil\appdata\local\programs\python\python37\lib\site-packages\pip (python 3.7)

It's happening also on travis : https://github.com/tdevilleduc/chaostoolkit-kubernetes/runs/592029162

I've manage to get rid of this early today but reinstall python (downgrade to 3.7.5) but it appends again. The only thing I've done by then is to rebase my repo from this one

Did you ever add this behaviour ?

Hi,
I've encountered a similar error message in an WSL/Linux environment when setting up a new venv to test out a few things. As a temporary/local workaround I downgraded pytest to a 5.3.x version, which worked for me. There seems to be an issue with pytest-sugar and pytest 5.4.x: Teemu/pytest-sugar#187

Cheers, Hendrik
