I was playing around with different flake8 plugins today and after uninstalling one of them and installing a new one, flake8 --version no longer works for me.
the flake8 packages I had at the time were
(python3) $ flake8 --version 3.8.4 (flake8-bugbear: 20.11.1, mccabe: 0.6.1, naming: 0.11.1, pycodestyle: 2.6.0, pyflakes: 2.2.0) CPython 3.8.2 on Darwin
after which I had ran
pip uninstalled flake8-bugbearpip install flake8-docstringspip uninstall flake8-docstringspip install flake8-comprehensionsIt now breaks with this error on flake8 --version
(python3) $ flake8 --version

I've already tried uninstalling & reinstalling flake8 with no luck. I assume that something is broken on the documentation stuff since doing flake8 --help will also throw this error
It seems one of the plugins had added a config parser and changed one of the configuration files. When uninstalled the parser was removed but it left the changes in config file(s).
You need to run through all flake8 config files and remove config sections for uninstalled plugins.
