Error running flake8

Since a while (~1 week) I get permanent problems with running flake8 inside of Atom:

linter-registry.js? [sm]:137 [Linter] Error running Flake8 Error: /bin/sh: module: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `module'
/bin/sh: ml: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `ml'

I have tried reinstalling linter, linter-flake8 couple of times with no luck, so I need to keep it disabled.

Flake executable is present and working by itself correct.

It’s because python 3.7 causes an error for old syntax. So you can wait till it will be fixed or install python 3.6.6

I was having the same issue after recently updating my python packages. Running: python -m pip install flake8 fixed the issue for me
