It seems that flake flake8 expects an argument called output_file as opposed to filename: https://github.com/PyCQA/flake8/blob/master/src/flake8/formatting/base.py#L48

$ pip freeze | grep "flake8"

flake8==3.8.4
flake8-bugbear==20.11.1
flake8-rst==0.7.2

$ python --version

Python 3.7.7

Has anyone run into this?

Oh, see https://github.com/kataev/flake8-rst/issues/22. This package is just not maintained.

[Olshansk]

So should I just send a PR to fix the --output-file and --filename discreptency?

[skirpichev]

You could try to install the flake8-rst from the master branch and test. Your issue should be fixed.

Then, wait for a while if the new version will be released...

[skirpichev]

Perhaps, this can be closed, as flake8-rst==0.8.0 was released. @Olshansk, can you confirm?
