INTERNALERROR after upgrading to Python to 3.8.2

[romulo-dbts]

Hi there,

After upgrading my Python version to 3.8.2 I stated getting the following error when running my test suit. Removing pytest-sugar my test suit runs normally.

Command used to run py.test

pytest my_project

$ pytest my_project

[RonnyPfannschmidt]

this is a known issue in combination with pytest 5.4.x that will be fixed in pytest 5.4.2

[romulo-dbts]

Hi @RonnyPfannschmidt thank you for replying me so quick and letting me know about the plans for fixing it.

[RonnyPfannschmidt]

Im on mobile so i can't crosslink the related issues on this tracker

[romulo-dbts]

@RonnyPfannschmidt I believe that you are talking about this one #187, right?

[RonnyPfannschmidt]

Exactly, thank you

[Ambro17]

Just came here to say i experienced the same bug with python 3.7 and pytest-sugar==0.9.2

[Teemu]

I think this has been fixed right?
