pymacs：一般问题和安装问题

Question

我正在尝试为python开发设置emacs。

据我所读，建议使用python-mode.el，而不是Emacs 22.3中的默认python.el。所以我开始了新的冒险。

据我所知，python模式有几个依赖项，因此我需要安装rope、rope mode和ropemacs。除此之外，我还需要安装pymacs。

问：这是正确的吗？

这是我的新产品。emacs现在：

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(inhibit-startup-screen t)
 '(tab-width 4))
(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 )

(setq emacs-config-path "~/.emacs.d/")
(setq base-lisp-path "~/.emacs.d/site-lisp/")
(setq site-lisp-path (concat emacs-config-path "/site-lisp"))
(defun add-path (p)
  (add-to-list 'load-path (concat base-lisp-path p)))

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

(require 'psvn)

;; python-mode
;;
(setq auto-mode-alist (cons '("\\.py$" . python-mode) auto-mode-alist))
(setq interpreter-mode-alist (cons '("python" . python-mode) interpreter-mode-alist))
(autoload 'python-mode "python-mode" "Python editing mode." t)


(setq pymacs-load-path '(   "~/.emacs.d/site-lisp/rope"
                            "~/.emacs.d/site-lisp/ropemode"
                            "~/.emacs.d/site-lisp/ropemacs"))


(setq interpreter-mode-alist
      (cons '("python" . python-mode)
        interpreter-mode-alist)
      python-mode-hook
      '(lambda () (progn
            (set-variable 'py-indent-offset 4)
            (set-variable 'py-smart-indentation nil)
            (set-variable 'indent-tabs-mode nil)
            ;;(highlight-beyond-fill-column)
                    (define-key python-mode-map "\C-m" 'newline-and-indent)
            (pabbrev-mode)
            (abbrev-mode)
     )
      )
)


;; 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)

;; Search local path for emacs rope
;;

;; enable pymacs
;; 
(require 'pymacs)
(pymacs-load "ropemacs" "rope-")

现在，当我启动emacs时，我得到了一条错误消息：

("C:\\opt\\emacs-22.3\\bin\\emacs.exe")
Loading encoded-kb...done
Loading regexp-opt...done
Loading easy-mmode...done

An error has occurred while loading `c:/opt/cygwin/home/akong/.emacs':

File error: Cannot open load file, pymacs

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

让事情稍微复杂一点：

出于工作原因，我不得不使用Python2.4，但是我的电脑上安装了Python2.6，但是很明显rope不喜欢2.4，所以我没有运行setup.py。我解开/解压这些包并将这些文件放在~/.emacs.d/site-lisp下。默认情况下，如果在命令提示符下调用python，则它是python 2.4可执行文件。
