python - Emacs Python 自动补全

Question

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))

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:

![enter image description here][1]

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。

不要使用rope/pymacs 来完成Emacs 的python，我建议使用https://github.com/tkf/emacs-jedi ，这真是太棒了。

你可以安装jedi使用 el-get( https://github.com/dimitri/el-get )，它将为您安装必要的依赖项。

我的 .emacs 绝地配置:

;;; jedi completion
;;; see https://github.com/tkf/emacs-jedi

;; jedi dependency: deferred
(add-to-list 'load-path (expand-file-name
                         "~/.emacs.d/el-get/deferred"))
;; jedi dependency: deferred
(add-to-list 'load-path (expand-file-name
                         "~/.emacs.d/el-get/ctable"))
;; jedi dependency: epc
(add-to-list 'load-path (expand-file-name
                         "~/.emacs.d/el-get/epc"))
(add-to-list 'load-path (expand-file-name
                         "~/.emacs.d/el-get/jedi"))
(require 'jedi)
(setq jedi:server-args
      '("--sys-path" "/usr/lib/python2.7/"
        "--sys-path" "/usr/lib/python2.7/site-packages"))

(setq jedi:setup-keys t)
