Vim shows python errors on exit

Question

Every time I try to exit vim, it shows me all of the errors in python. I do not want this. This is a screenshot of what I am talking about.

How can I fix this? TIA.

This seems to be output from vim-flake8 plugin. You probably need to uninstall or disable the plugin, or remove autocommand that runs flake8 on saving Python file.

I cannot give more detailed answer — I need to see your .vimrc and perhaps the content of .vim directory.

If you don't want to disable vim-flake8 but only want to get rid of its output on exit — add this to your .vimrc:

" automatically close quickfix if it's the only window left"
autocmd WinEnter * if winnr('$') == 1 && &buftype == "quickfix" | quit | endif
