Failed to load Python host.

[mmtechslv]

I installed vim-rainbow_csv using vim-plug. However, when I press F5 I get the following error:

function provider#python#Call[9]..remote#host#Require[10]..provider#pythonx#Require[13]..provider#Poll, line 4 Vim(if):Error invoking 'poll' on channel 8:^@ch 8 was closed by the client Failed to load python host. You can try to see what happened by starting nvim with $NVIM_PYTHON_LOG_FILE set and opening the generated log file. Also, the host stderr is av ailable in messages. Press ENTER or type command to continue

I did pip install rbql, but it did not fix anything. What could be the cause of this error?

My guess is that it could be something wrong with your neovim installation, I tried to google your error and found some results. Do other python-based plugins work correctly in your editor? If nothing helps, you can set a special variable let g:rbql_use_system_python=1 in your vim config. I just added this config option, so you would need to update rainbow_csv first in order to use it, see my last commit. After this Vim/Neovim will use system python interpreter instead of the built-in one. Please let me know if it doesn't work. PS you don't have to pip install rbql, it is already built-in into rainbow_csv.

Thank you for the quick response! Updating the plugin and setting the special variable helped. It works now without errors. Thanks! Note: I am not sure what plugins I use are based on python but I have not received any similar error.

I am glad it worked, @mmtechslv !
