[yogrr]

how did you install flake8?

$ poetry install --no-root

unmodified output of flake8 --bug-report

{
"can't be reached": "parsing arguments is crashing"
}

describe the problem

what I expected to happen

To lintcheck my porject folder when launching flake8 under .venv by poetry

commands ran

$ flake8 (same output as underlying)
$ flake8 --bug-report

this is not us. read the file in the stacktrace where the error occurs and track down that plugin
