Emacs Jedi auto-complete not working on init

Question

I installed jedi along with some other packages via el-get the other day, and initially it all worked great (auto-completion, popup menus etc).

In the past few days, however, jedi has stopped working (i.e. auto-completion, popups and function argument suggestion no longer work).

I've discovered part of the reason for this not working is that, for some reason, auto-complete is not enabled on startup. I've tried adding (setq auto-complete-mode t) to my .emacs file both before and after el-get loads jedi, but despite enabling auto-complete, it still doesn't work for some reason. Instead, I have to enable auto-complete using M-x auto-complete-mode once emacs has loaded (I have also tried the suggestions here Emacs auto-complete-mode at startup, but that just throws a load of errors when emacs loads).

Besides this, when I type M-x jedi RET, some of the commands listed on the jedi troubleshooting page (such as jed:setup-keys) seem to be missing.

I also seem to be experiencing the same problems as this guy here: emacs-jedi does not find numpy completions, but I'm not sure if the two problems are linked.

Answer 1

I had the same problem with the auto-complete-mode. I had to manually start it.

Being a total newbie I struggled with it for a while but deduced a solution. Maybe it's not very elegant, but it works... Add it as a hook to the python-mode before enabling jedi ac.

;;enable jedi autocompletion in python
(add-hook 'python-mode-hook 'auto-complete-mode)
(add-hook 'python-mode-hook 'jedi:ac-setup)

Check out the troubleshooting section in the documentation first: http://tkf.github.com/emacs-jedi/#troubleshooting

I recommend you to start from make tryout as mentioned in the document, like this:

 curl -fsSkL https://raw.github.com/rejeep/carton/master/go | sh
 make CARTON=$HOME/.carton/bin/carton tryout

From the document:

This will install requirements for Jedi.el separated from your local setup in .emacs.d. You can also check the configuration file tryout-jedi.el which is used by make tryout to see the minimum working configuration. If you have trouble setting up Jedi.el, compare your configuration file and tryout-jedi.el.
