Error when running on python 3.7

See original GitHub issue

Hey, homebrew upgraded my python to 3.7 and since the linter stopped woking, spitting out this error:

[Linter] Error running Flake8 Error: /usr/local/lib/python3.7/site-packages/ FutureWarning: Possible nested set at position 1
  EXTRANEOUS_WHITESPACE_REGEX = re.compile(r'[[({] | []}),;:]')

When I run flake8 manually in project it gives the same message as a warning and then runs normally

for Python 3.7.2 (both Anaconda version and brew installed version) with:

  • pep8==1.7.1
  • pycodestyle==2.4.0

Update this line:

EXTRANEOUS_WHITESPACE_REGEX = re.compile(r'[\[({] | [\]}),;:]')

in BOTH: lib/python3.7/site-packages/ lib/python3.7/site-packages/

I resolved this by reinstalling flake8.

pip3 install --force flake8

Upgrading to the latest version might also help for others.

pip3 install --upgrade flake8
