Can't get the jedi-vim plugin to work

Question

I'm trying to use the jedi-vim plugin for Python autocompletion but I can't get it to work.

I have Vim 7.3, and here's what I did:

1- clone the code from

git clone http://github.com/davidhalter/jedi-vim path/to/bundles/jedi-vim

2- copy jedi-vim/plugin/jedi.vim to ~/.vim/plugin/

3- copy jedi-vim/doc/jedi-vim.txt to ~/.vim/doc/

Now when I open vim, enter the insert mode and type

import wave
wave.

nothing happens, though the doc specify Autocompletion is also triggered by typing a period in insert mode, and if I try <Ctrl-Space> I get the following error

E29: No inserted text yet
Press ENTER or type command to continue

I checked :map and it seems that <Ctrl-Space> is not used:

n  [m          *@:call <SNR>21_Python_jump('?^\s*\(class\|def\)')<CR>
n  [[          *@:call <SNR>21_Python_jump('?^\(class\|def\)')<CR>
n  ]m          *@:call <SNR>21_Python_jump('/^\s*\(class\|def\)')<CR>
n  ]]          *@:call <SNR>21_Python_jump('/^\(class\|def\)')<CR>
n  gx            <Plug>NetrwBrowseX
n  <Plug>NetrwBrowseX * :call netrw#NetrwBrowseX(expand("<cWORD>"),0)<CR>

Since I got an error using <Ctrl-Space>, I guess it must do something, right? Why can't I see it with :map?

What am I missing?

I updated Vim to 7.4 and installed vim-jedi using pathogen as described in the doc:

1- install jedi 2- install pathogen 3- add execute pathogen#infect() in my ~/.vimrc 4- clone git repository in ~/.vim/bundle/

I create a new file, and I still have no autocompletion. Eg:

import numpy as np
np.

and control+space in insert mode returns:

-- Omni completion (^O^N^P) Pattern not found

Is there any omni completion plugin conflicting? I haven't installed such plugin...

Should I had anything else to my ~/.vimrc file?

Answer 1

This is the basic installation of Jedi with Pathogen.

1. Install Pathogen

   mkdir -p ~/.vim/autoload ~/.vim/bundle && \
   curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim
   

2. Configure.vimrc
   if you have a ~/.vimrc file: add the following line to it

   execute pathogen#infect()
   

   else: create a blank file named .vimrc at your home folder and add the following lines to it.

   execute pathogen#infect()
   syntax on
   filetype plugin indent on
   

3. Install Jedi.

   cd ~/.vim/bundle/ && git clone --recursive https://github.com/davidhalter/jedi-vim.git
   

4. enjoy!

   

Answer 2

I had a similar error because of a mismatch between the python version I intended to use and the one that was called.

Make sure jedi is using the intended version of python. E.g. add let g:jedi#force_py_version = 3 to your .vimrc
