How to use semshi in venv?

[sumarokov-vp]

When I try to open python file with enabled venv (source venv/bin/activate), I have some errors:

function 10_filetype_changed[4]..remote#define#CommandBootstrap[1]..remote#host#Require[10]..provider#pythonx#Require[14]..provider#Poll:

Failed to load python3 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 available in messages.

E171: Отсутствует команда :endif

You should set g:python3_host_prog properly (in your init.vim). This is an example how you can assign it dynamically:

let g:python3_host_prog = substitute(system("which python3"), '\n\+$', '', '')

This will set a path to the python3 exectuable that can be found in your $PATH.

(Note however that activating a virtualenv typically adds it to $PATH, and it sounds like it is not wanted to use the venv, to not have to install pynvim there then also.)
