Issue

Unable to launch jedi-vim. Error is:

After typing :messages, I get

jedi-vim error: jedi#setup_python_imports: Traceback (most recent call last):
  File "<string>", line 10, in <module>
ModuleNotFoundError: No module named 'jedi_vim'

Steps to reproduce

Running Vim 8.2 on Windows 10 with +python3/dyn. Installed Python is 3.9.

Can confirm that echo has('python3') returns 1.

Running :python3 import sys; print(sys.version)' returns 3.9.10 (tags/v3.9.10:f2f3f53, Jan 17 2022, 15:14:21) [MSC v.1929 64 bit (AMD64)]`.

Can confirm this matches the output of running python --version.

Installed jedi-vim into .vim/pack/plugins/start via git clone --recursive. Subsequently ran git submodule update --init --recursive.

The minimal.vimrc I used:

set nocompatible

let script_dir = fnamemodify(expand('<sfile>'), ':h')
let &runtimepath .= ','.script_dir.','.script_dir.'/after'

" Put your config changes here.
" let g:jedi#show_call_signatures=1

set pythonthreehome=C:\<path-to>\python3.9\\latest
set pythonthreedll=C:\<path-to>\python39.dll

syntax on
filetype plugin indent on

Opening a .py file then produces the error.

I have no idea what's wrong here.

Since jedi_vim_debug is not found, I feel like there's something wrong with your VIM installation. It's definitely a new issue that I haven't seen before.

[cesarosum]

OK I will try reinstalling VIM as a first step and report back if the issue persists.

[cesarosum]

I tried reinstalling VIM but the error persists.

I have also tried installation using Vundle but again no luck.

[davidhalter]

It's strange, because you seem to be the only person that has this issue.

[cesarosum]

Yeah it's a doozy :-)

For what it's worth, I created a .pth file in Lib\site-packages containing the path to jedi-vim\pythonx under the assumption that the problem was that python simply didn't know where to look. Got the following errors now -

And indeed, the output of :python3 import os; for key in os.environ.keys(); print(key) yields

ANSICON
ANSICON_DEF
CONEMUANSI
PATH
SYSTEMDRIVE
SYSTEMROOT
WINDIR

HOME is noticeably absent.

[davidhalter]

This looks like something's broken with either Python3 or VIM, but I have a very limited knowledge about that interaction. Maybe reinstalling Python3.9 from a different source?

well i have the same issue :)
