编辑：
我刚刚意识到我正在使用 0.2 版的 auto-complete.el。我想我需要使用 auto-complete.el 0.1 版。我可以从哪里下载它？我只能在谷歌上找到较新的版本。
我正在尝试在 Emacs 中为 Python 设置自动完成功能。
我使用的是 Ubuntu LTS 版本，我安装了 Python 和 Emacs。
这是我的 .emacs 文件：
(setq-default indent-tabs-mode nil) ; always replace tabs with spaces
(setq-default tab-width 4) ; set tab width to 4 for all buffers
(add-to-list 'load-path "~/.emacs.d/vendor")
(progn (cd "~/.emacs.d/vendor")
(normal-top-level-add-subdirs-to-load-path))
(require 'python)
(require 'auto-complete)
(require 'yasnippet)
(autoload 'python-mode "python-mode" "Python Mode." t)
(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
(add-to-list 'interpreter-mode-alist '("python" . python-mode))
;; Initialize Pymacs
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)
;; Initialize Rope
(pymacs-load "ropemacs" "rope-")
(setq ropemacs-enable-autoimport t)
;; Initialize Yasnippet
;Don't map TAB to yasnippet
;In fact, set it to something we'll never use because
;we'll only ever trigger it indirectly.
(setq yas/trigger-key (kbd "C-c <kp-multiply>"))
(yas/initialize)
(yas/load-directory "~/.emacs.d/snippets")

在 .emacs.d 目录中，我有：
pymacs.el
init_python.el
vendor/
snippets/
在 .emacs.d/vendor 我已经安装了 pymacs、yasnippet 和 auto-complete，所以它看起来像这样：
auto-complete.el
pinard-Pymacs-4be2c15/
yasnippet-0.5.9/
当我像这样启动emacs时：
emacs -nw manage.py
我收到此错误消息：

任何想法如何让它工作？
我已经在谷歌上搜索了很长时间，但我找不到任何明确的说明如何让它们一起工作。
