Issue Details

With opening any python file I get

YouCompleteMe unavailable: 'encoding' is an invalid keyword argument for this function

To reproduce it just open python file even empty or new buffer with .py extension.

I tried to reinstall YouComleteMe totally by removing folder from ~/.vim/bundle and installing with vim +BundleInstall and then ./install.sh --clang-completer. But it didn't help.

Currently I use vim from brew, but I tried to use MacVim too. There is the same issue.

Similar issue: https://github.com/Valloric/YouCompleteMe/issues/2024

Can't call :YcmDebugInfo and :YcmToggleLogs stderr because of E492: Not an editor command: .... Also with opening python files in the temp folder (in my case /var/folders/16/dcxbn15x0pjfm7wt7b8mm52r0000gn/T/ycm_temp logs do not appear). With opening any other file logs appears.

What is the output of :py import pprint; pprint.pprint( sys.path ) in Vim?

[micbou]

Thanks. This is a compatibility issue between YCM and the flake8-vim plugin. The former uses python-future for Python 2 and 3 support while the latter uses pies. These two packages don't work well together. Unfortunately, I don't see an easy way to prevent this. I suggest to use syntastic instead of flake8-vim or ask the flake8-vim author to not depend on pies.

[Gray-Wind]

Thanks a lot, autocompleting works without flake8.

you can use codecs module in python for this.
import codecs
f = codecs.open('file_name.txt', 'r', 'UTF-8')
