Windows 8 + Emacs 24.3 + emacs-for-python:Pymacs helper在30秒内没有启动

我最近安装了Emacs 24.3,并尝试使用Python编码(v3.3.2 x86-64 MSI安装程序)。 (我是Emacs的新手)。 然后,我尝试通过解压缩zip来安装emacs-for-python

"C:\Users\mmsc\AppData\Roaming\.emacs.d\emacs-for-python" 

文件夹并添加

 : (load-file "~/.emacs.d/emacs-for-python/epy-init.el") 

到C:\ Users \ mmsc \ AppData \ Roaming.emacs

在我启动Emacs之后,我看到错误

警告(初始化):加载`c:/Users/Klein/AppData/Roaming/.emacs'时发生错误:

错误:Pymacs帮手没有在30秒内开始

为确保正常操作,您应该调查并删除初始化文件中错误的原因。 用`–debug-init'选项启动Emacs来查看完整的错误回溯。

用“–debug-init”,我看到下面的信息,但是我对Emacs / Lisp知之甚less,所以我找不到这个问题。

我试图从互联网search一些帮助,但其中大部分是为Linux / Unix环境。 有没有人在Windows下使用Python的Emacs,知道这意味着什么,我该如何解决?

谢谢!

这太有点评论了:

  (let ((process (apply 'start-process "pymacs" buffer (let ((python (getenv "PYMACS_PYTHON"))) (if (or (null python) (equal python "")) pymacs-python-command python)) "-c" (concat "import sys;" " from Pymacs import main;" " main(*sys.argv[1:])") (append (and (>= emacs-major-version 24) '("-f")) (mapcar 'expand-file-name pymacs-load-path))))) 

这是在*Pymacs*缓冲区启动进程的Pymacs代码。 您可以从中推断出Pymacs将首先搜索环境变量$PYMACS_PYTHON ,如果这个变量不存在或者它的值是空字符串,那么它将尝试pymacs-python-command ,默认为"python" 。 所以,它会打这个电话:

 $ python -c 'import sys; from Pymacs import main; main(*sys.argv[1:])' 

-f我不知道Python的哪个版本接受这个参数,但是我没有。 这段代码的意图是非常清楚的 – 可能它需要加载pymacs-load-path的文件,但对于我来说这个变量的值是nil – 所以我不认为这个代码运行。 无论如何,这个论点似乎没有什么坏处,因为这个论点有点不一样。

所以,如果你尝试在控制台上运行上面的命令,并得到如下所示:

 (version "0.25") 

然后这个代码工作正常,否则,你会得到一些错误,这将有助于你找出问题。 请记住,它可能不只是python 。 它是$PYMACS_PYHONpymacs-python-command

我有同样的症状,但我的问题原来是一个旧的pymacs.el和一个新的Pymacs。 很明显Pymacs改变了模块界面,我不得不去寻找流氓pymacs.el。 所以pymacs.el被apt-get安装在一个奇怪的位置。 你必须确保字节码文件也没有了。
