python 3.9 flake8 plugin doesn't work and throws error. #73

Open vikigenius opened 3 years ago

vikigenius commented 3 years ago

So I enabled the flake8 plugin as described in the CONFIGURATION.md

But opening a python files throws the following error and the plugin doesn't work.

Installing the 3rd party flake8 plugin pyls-flake8 does not fix the issue either.

@vikigenius With what editor do you see this? Are you still able to reproduce with latest versions of flake8 and pylsp? Using (doom) emacs and latest versions I can't reproduce.

The error seems to have gone now, but it doesn't actually seem to be using the plugin anymore.

So now if you install the pyls-flake8 plugin from https://github.com/emanspeaks/pyls-flake8/, you can see a different error which complains about incorrect flake8 usage
