Error: jedi-vim failed to initialize Python: jedi-vim requires Vim with support for Python 3. (in function jedi#init_python[4]..<S NR>41_init_python, line 4)

Issue

I get the following error (see further below for the full output from JediDebugInfo!):

Error: jedi-vim failed to initialize Python: jedi-vim requires Vim with support for Python 3. (in function jedi#init_python[4]..<S
NR>41_init_python, line 4)

However, when I press enter at the prompt, it works as usual.

Note that I'm using Neovim.

Steps to reproduce

Only happens for me when I add the following. The problem disappears when this one line is removed (from init.vim):

" ... more stuff
language en_US
" ... more stuff

(My $LANG variable, if it helps: LANG=sv_SE.UTF-8.)

And then open a Python file to invoke jedi-vim.

Output of “:verbose JediDebugInfo”

Found the issue. Use en_US.UTF-8 instead. 🤦 . Closing.

mazunki commented 2 years ago

I just arrived at this same error, but it wasn't related to language at all. Had to pip install pynvim. Also, nvim doesn't know 3.10 is newer than 3.9, so if you're using 3.10 you should make pip install it through python3.9 -m pip install ...

blueyed commented 2 years ago

@mazunki "jedi-vim requires Vim with support for Python 3" for Neovim implies that pynvim might be missing, yeah - maybe it could have a clearer error message in that case.

As for "nvim doesn't know 3.10 is newer than 3.9": this should not really matter, does it? Or is it due to nvim picking 3.9 over 3.10? IIRC it should prefer the first one with pynvim / that works, but is certainly more an issue for/with nvim.

Re: @blueyed

I have Python 3.9 and Python 3.10 installed on my computer. python3 symlinked to python3.10. Thus pip install --user pynvim installs pynvim for Python 3.10. Since python3 (that is, 3.10) is inferior to Python 3.3 or whatever it demands as a minimum, it goes to the next option: Python 3.9. Seeing as pip hasn't installed pynvim for Python 3.9, but only Python 3.10, it claims I don't have it anywhere.

If Neovim knew Python 3.10 was a valid Python version, it would work to just pip-install it as normally, without having to call the module from within the specific subversion. Python 3.10 is still not fully released, though.

In regards to the error message, yeah. It would be nice for it to hint at :checkhealth provider, although I quickly found that through a search.
