使用el-get安装emacs-jedi时出现包加载问题

Question

I've followed these instructions with el-get to try to install emacs-jedi (and the other needed packages), but no luck.

In my .emacs file, I've added the following lines:

;; .emacs

;; Load package repositories
(require 'package)
(add-to-list 'package-archives
             '("marmalade" . "http://marmalade-repo.org/package/") t)

(add-to-list 'package-archives
             '("melpa" . "http://melpa.milkbox.net/packages/") t)

;; Install / load / require el-get and
;; packages managed by it.
(add-to-list 'load-path "~/.emacs.d/el-get/")
(add-to-list 'load-path "~/.emacs.d/el-get/el-get")

(unless (require 'el-get nil t)
  (url-retrieve
   "https://raw.github.com/dimitri/el-get/master/el-get-install.el"
   (lambda (s)
     (end-of-buffer)
     (eval-print-last-sexp))))

;; Initialize any loaded packages 
(package-initialize)

;; stuff to set font, theme, etc.
;; ...

;; Include jedi for Python mode.
(add-hook 'python-mode-hook 'jedi:setup)
(setq jedi:complete-on-dot t)

;; rest of file ...

At first, I was seeing the issue "cannot open load file jedi/jedi." This seemed to go away when I added "~/.emacs.d/el-get/" to the load path ( el-get seems to only place "~/.emacs.d/el-get/el-get" on the load path when installing).

But after this, opening a Python file and trying Mx python-mode yields an error:

Symbol's function definition is void: jedi:setup

I'm happy to do any more debugging or to provide more messages or output -- but after Googling for these error messages for a long time, I have been unable to find anything to try that seemed productive.

You are missing (el-get 'sync) which is mentioned in https://github.com/dimitri/el-get#basic-setup

Also, you don't need (package-initialize) etc. for package.el setup. Everything is handled by el-get. It is a good idea to not mix two package managers.

Here is a minimal Emacs setup to use Jedi via el-get:

(add-to-list 'load-path "~/.emacs.d/el-get/el-get")

;; Uncomment this, if you are in hurry
;; (setq el-get-install-skip-emacswiki-recipes nil)

(unless (require 'el-get nil 'noerror)
  (with-current-buffer
      (url-retrieve-synchronously
       "https://raw.github.com/dimitri/el-get/master/el-get-install.el")
    (goto-char (point-max))
    (eval-print-last-sexp)))

(el-get 'sync)

(add-hook 'python-mode-hook 'jedi:setup)
(setq jedi:complete-on-dot t)

;; Type:
;; - M-x el-get-install RET jedi RET
;; - M-x jedi:install-server RET
;; Then open any Python file.

Update:

I added it in the manual
