Behaviour

Expected Behavior

Ability to control which flake8 I'm running in which venv in which path - per project - in a WSL environment.

Actual Behavior

Flake8 server fails with cryptic error message

Extra Details

I think the ENOENT is actually the flake8.cwd path - not anything to do with the server/python path. When I change that one setting back to ${cwd} the server starts fine (and gives me the wrong flake8 errors because it's not finding the sub-projects tox.ini). I think ${fileDirname) must be sending the flake8 server (which I think IS running in the WSL venv) to use a cwd with a c:\-style path instead of the /mnt/c-style path and the python flake8 server running under WSL can't find it? Just a guess, cause ${relativeFileDirname} fails the same way but an explicit /mnt/c/Users/cgerrard/Workspace/vagrant-swift-all-in-one/works and I can't get any additional debug/trace information. Is there WSL compatible versions of ${fileDirname}?
