I am running on Ubuntu 12.04 with Vi IMproved 7.3 (2010 Aug 15, compiled May 4 2012 04:25:35). Jedi version 0.8.1-final0. Jedi-vim was installed using pathogen. Whenever I run ":help jedi-vim" I get "E149: Sorry, no help for jedi-vim". Running help on all other plugins I have works like a charm.
Hmm, it works for me (also using pathogen). Anybody else?
If it helps I use these plugins: conque_term, ctrlp, tlib and vim-addon-mw-utils.
But jedi-vim itself works?
jedi-vim works partially. It gives me the list of auto-completes, docs work, usages and gotos work - but only limited to a single file. Sometimes it is limited to a file, sometimes its not. One of the biggest annoyances that I can't fix is the 
usages is still kind of broken. Do not trust it too much. It's also hard to find all usages anyway. I cannot really help you with the docs issue.
I would really be interested if anyone else has that same problem as well.
I am having the same error as far as I can tell. I'm just starting the process of trying to use vim as my main editor, so I can't be quite as helpful as ayeganovgb, but I am using pathogen and jedi only. Funnily enough, :helpg jedi pops up jedi-vim.txt.
This is also happening to me. I installed using pathogen, and my one other pathogen plugin continues to work fine.

However, neither :help jedi-vim nor any of the commands work.
You seem to use pathogen. Are you calling pathogen#helptags() in your vimrc?
True! :)
@ayeganov
Can you please report back?
I don't run pathogen#helptags in vimrc. Actually I recently did a full disk wipe, and installed xubuntu. This problem is no longer present.
