Error: jedi-vim failed to initialize Python (again, I'm afraid)

See original GitHub issue

Issue

I have two machines – a gentoo 64 bit and a gentoo 32 bit.

I also have the problem: Error detected while processing function jedi#init_python: line 7: Error: jedi-vim failed to initialize Python: jedi#setup_py_version: failed to run Python for initialization: Vim(python3):Traceback (most rece nt call last):. (in function jedi#init_python[3]…<SNR>69_init_python[50]…jedi#setup_py_version, line 25)

Here is what is funny. Vim-jedi seems to work on the 32 bit machine. I just git-cloned into ~/.vim/bundle.

On the 64 bit machine I was fooling around with vim and to my surprise for the first time I could start gvim with no arguments without the above message. Then to my surprise I could type in a tiny file ~/t.py that printed the sys.path. The vim-jedi completion worked for the first time.

Then I did a little test: leave the editor and type gvim ~/t.py to reenter. To my surprise there was no message, and the line completion worked.

After that, vim-jedi quit working in the smae manner. The same message comes up when t.py is edited, either by ‘gvim ~/t.py’ or by :e ~/t.py.

When I said “fooling around” above, what I am really saying is that I don’t know of anything I did to make vim-jedi start working, and I don’t know of anything I did to make jedi-vim stop working. But I’m pretty sure I that I am accurately describing what happened.

So it appears that there is indeed some subtle bug that could be on the vim side. Or it could be on the python side. The combination of vim and python does not seem to be acting in a deterministic fashion. That kind of argues against the usual “configuration error” scenario. It is something else.

Is there any way to debug the python code called by vim?

Thanks in advance.

Steps to reproduce

As I said above, the lack of any steps is the real point.

My .vimrc:

let PathVimConfig = “/home/me/.vim/config/”

" VIM.Plugin.Pathogen " This command says to load ~/.vim/autoload/pathogen.vim and run infect(). " execute pathogen#infect() call pathogen#helptags()

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

syntax on filetype plugin indent on

Output of “:verbose JediDebugInfo”

You should run this in a buffer with filetype “python”.
