Flake8 extension crashing

[bmakan]

I've installed the extension for the first time to see how it works as opposed to the native flake8 linting. But nothing was happening. I found an error in there (see trace below).

Without the extension, the linting works correctly. I use multiple flake8 plugins (https://github.com/wemake-services/wemake-python-styleguide to be exact).

@bmakan This is an issue with flake8_bandit see tylerwince/flake8-bandit#41 . flake8 version 5.0.0 dropped support for ConfigFileFinder.

Try the following, and it might work for your case:

1. Install flake8 version 4.0.1 in your environment.
2. Install flake8_bandit.
3. Set flake8.importStrategy to fromEnvironment
