python - Windows 上 emacs 中的 pyflakes 问题

我点击了这个链接 here尝试在 Windows 上为 python dev 设置 emacs。虽然一切看起来都很好,但 pyflakes 正在制造问题并且没有给我语法检查。每次打开“.py”文件时,我都会收到错误“无法使用参数‘foo.py’启动语法检查进程‘pyflakes’:搜索程序:没有这样的文件或目录 pyflakes”

谁能帮我解决这个问题?

更新:

这是我的.emacs

;; Abhi's  c:\.emacs file


(add-to-list 'load-path "C:/emacs/colors/")
(require 'color-theme)
(eval-after-load "color-theme"
'(progn
(color-theme-initialize)

(defun sacha/decrease-font-size ()
(interactive)
(set-face-attribute 'default
nil
:height
(floor (* 0.9
(face-attribute 'default :height)))))
(global-set-key (kbd "C-+") 'sacha/increase-font-size)
(global-set-key (kbd "C--") 'sacha/decrease-font-size)

;muse mode mappings
(add-to-list 'load-path "C:/emacs/Muse/muse-latest/lisp/")

(require 'muse-mode)

;To do list mode config
(add-to-list 'load-path "C:/emacs/lisp/")

;a simple function that opens the file,

最佳答案

终于成功了!

感谢 phils 为我指明了正确的方向。谷歌搜索后,发现 this并在谷歌翻译器(该页面为俄语)的帮助下终于能够进行语法检查!

英文详细信息:

以通常的方式安装 pyflakes 后,执行以下操作:

  1. 使用以下代码在 _YourPythonRootDir_\Scripts 中创建名为 runpyflakes.py 的文件:

    from pyflakes.scripts.pyflakes import mainmain()
  2. _YourPythonRootDir_\Scripts 中使用以下行创建名为“pyflakes.bat”的文件:

    @_YourPythonRootDir_\python.exe _YourPythonRootDir_\Scripts\runpyflakes.py %*
  3. _YourPythonRootDir_\Scripts添加到“Path”环境变量

问题解决了!!!

注意:_YourPythonRootDir_=您系统上 Python 根目录的路径。在我的 C:\Python26\

当然要感谢 Phils、Starkey 和 gelvaos!!!
