我在这里按照此链接尝试在 Windows 上为 python dev 设置 emacs。尽管一切看起来都很好，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，我都会收到错误消息“无法使用 args '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？

这是我的 .emacs

Got it to work finally!

Thanks to phils for pointing me in the right direction. After googling, found this and with the help of google translator (The page is in Russian) was able to finally get syntax checking to work!

Details in english:

After installing pyflakes the usual way, do the following:

  1. Create file called runpyflakes.py in _YourPythonRootDir_\Scripts with the following code:

    from pyflakes.scripts.pyflakes import main
main()

  2. Create file called "pyflakes.bat" in _YourPythonRootDir_\Scripts with the following lines:

    @_YourPythonRootDir_\python.exe _YourPythonRootDir_\Scripts\runpyflakes.py %*

  3. Add _YourPythonRootDir_\Scripts to the "Path" environment variable

PROBLEM SOLVED!!!

Note: _YourPythonRootDir_=path to Python's root directory on your system. In mine its C:\Python26\

Thanks Phils,Starkey, and gelvaos of course!!!

如果您按照这些说明使用 apt-get ，那么我认为这不是权限问题*，所以听起来 emacs 只是看不到可执行文件。

flymake 调用在目录 ( )start-process中查找程序exec-pathC-hv exec-path RET

您可以(add-to-list 'exec-path "~/bin")在 .emacs 中放置类似的内容，以使相应的目录可见。

(*) 如果您没有使用包管理器 OTOH 安装它，那么我也会检查权限。
