I've got my vim configs stored in subversion, at https://stromberg.dnsalias.org/svn/vimrc/trunk
I use it frequently on linuxes. It works great for editing Python code; I use pyflakes, pydocstyle and pycodestyle.
I am doing a Windows+Linux project lately, so I wanted to use this vim config on Windows 10 too. It does pydocstyle and pycodestyle well, but pyflakes is ignored for some reason, even if I intentionally put in something I know pyflakes should complain about - but as I mentioned, pyflakes only fails on Windows, not Linux. And I want to use pyflakes on Windows.
I've been staring at this for hours, but I'm not seeing why pyflakes fails when pydocstyle and pycodestyle are happy.
If I run: python3 -m pyflakes t.py
...at the command line, things seem to work fine, even on Windows 10. There are errors caught, and the exit code is 1.
Here's my t.py:
#!/usr/bin/env python3
"""Scrutinize how pyflakes is working."""
def main():
"""Scrutinize how pyflakes is working"""
fred = 1
print('hi')
print(barney)
main()
I tried export LC_CTYPE=en_US.UTF-8
...in an MSYS bash, prior to editing t.py. The errors from pyflakes were still ignored.
I also tried enabling syntastic debugging, with:
let g:syntastic_debug_file = "~/syntastic.log"
let g:syntastic_debug = 3
...in my ~/_vimrc (the name is changed on Windows).
This results in the following in ~/syntastic.log:

...but even that doesn't appear to tell me what's wrong.
This is the point where, on Linux, I'd probably turn to strace.
BTW, the vimrc is at https://stromberg.dnsalias.org/svn/vimrc/trunk/hierarchy/.vimrc , and the most relevant portions are:
let g:syntastic_python_checkers = ['pyflakes', 'pycodestyle', 'pydocstyle']
function Py2()
let g:syntastic_python_python_exec = '/usr/bin/python'
endfunction
function Py3()
let g:syntastic_python_python_exec = '/usr/bin/python3'
endfunction
call Py3() " default to Python3
BTW, I tried changing the /usr/bin/python3 to simply 'python3' in my ~/_vimrc, but it didn't appear to help.
Oh, and :SyntasticInfo gives:

Any suggestions folks?
