(cryptography) ~/p/cryptography (master) $ pip freeze | grep flake8
flake8==3.0.0

This is fixed in master and will be in the next release. I'll look to release this week.

[alex]

Great, thanks.

[fxfitz]

Seeing this in our projects too. Waiting for latest release.

[pgjones]

I have just released 0.9, which should solve this issue.

Thank you @pgjones!

[fxfitz]

You're a gentleman and a scholar.

I got the same error. I am using flake8==3.3.0 flake8-pep257==1.0.5

[pgjones]

@shibasisp I think your error is most likely related to flake8-pep257 which looks to be abandoned now https://github.com/Robpol86/flake8-pydocstyle. I would change to use https://gitlab.com/pycqa/flake8-docstrings as it recommends instead.

[shibasisp]

Oo Thanks @pgjones. It's working now!
