从命令行(emacs filename.py)运行时,flymake和pylint完美地协同工作.错误被正确突出显示. (虽然我无法工具提示悬停以获取错误详细信息,因为它是文本模式.)
当从GUI(Carbon Emacs)运行时,Flymake立即返回,并且文件中的第一行突出显示错误“in< module>”.第一行甚至在“Hello World”脚本上显示错误.)我想让它在GUI模式下正常工作,这样我就可以用鼠标导航(我知道,我知道)并使用工具提示来获取详细信息关于pylint报告的错误.
我用“easy_install pylint”安装了pylint,pylint和epylint脚本在“〜/ py / scripts”中.我将该目录添加到我的.bashrc中的PATH中：
export PATH=$PATH:~/py/scripts(我的.profile是我的.bashrc的符号链接.)
我意识到Emacs-GUI没有从我的.bashrc加载路径,所以我创建了一个〜/ .MacOSX / environment.plist文件,用我在终端中看到的完整PATH设置PATH变量.
现在在Emacs-GUI“(getenv”PATH“)中”输出显示正确：
"/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11/bin:/Users/schof/py/scripts:/usr/X11R6/bin"同样,“C-h v exec-path”的输出显示正确：
("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/usr/local/bin" "/usr/local/git/bin" "/usr/X11/bin" "/Users/schof/py/scripts" "/Applications/Emacs.app/Contents/MacOS/libexec" "/Applications/Emacs.app/Contents/MacOS/bin" "/usr/X11R6/bin")这让我对如何解决这个问题没有进一步的想法.我绝不是一个emacs大师,所以我可能会遗漏一些明显的东西;随时可以询问更多细节.
OS X 10.6.7;碳Emacs 22.3.1; pylint 0.23.0.
来自.emacs的Flymake / Pylint代码：
(when (load "flymake" t) (defun flymake-pylint-init () (let* ((temp-file (flymake-init-create-temp-buffer-copy 'flymake-create-temp-inplace)) (local-file (file-relative-name temp-file (file-name-directory buffer-file-name)))) (list "epylint" (list local-file)))) (add-to-list 'flymake-allowed-file-name-masks '("\\.py\\'" flymake-pylint-init)));; Auto-start flymake-mode when you go into python-mode(add-hook 'python-mode-hook '(lambda () (setq python-indent 4) (flymake-mode)))更新2011-04-05以回应@ sanityinc的回答：
* message *中的flymake的详细级别3输出:(这不会使问题的根源对我来说很明显.)

要更清楚地看到出现了什么问题,请增加flymake的日志级别,然后查看* messages *：
(setq flymake-log-level 3)没有这些信息,我不会推测可能存在的问题.
有一个避免环境.plist方法,BTW的技巧;您可以让Emacs向您的常规shell询问您的首选路径：
(defun set-exec-path-from-shell-PATH () (let ((path-from-shell (replace-regexp-in-string "[ \t\n]*$" "" (shell-command-to-string "$SHELL --login -i -c 'echo $PATH'")))) (setenv "PATH" path-from-shell) (setq exec-path (split-string path-from-shell path-separator))))(when (and window-system (eq system-type 'darwin)) ;; When started from Emacs.app or similar, ensure $PATH ;; is the same the user would see in Terminal.app (set-exec-path-from-shell-PATH))(这是从my Emacs config开始的,其中包含一堆flymake代码,包括使用pyflakes的python配置,所以你可能想看看.)
更新：既然你已经添加了详细输出,我看到你的〜/ py / epylint程序找不到pkg_resources,它指向PYTHONPATH错误.因此,使用上述技术的变体,试试这个：
(defun setenv-from-shell (varname) (setenv varname (replace-regexp-in-string "[ \t\n]*$" "" (shell-command-to-string (concat "$SHELL --login -i -c 'echo $" varname "'")))))(setenv-from-shell "PYTHONPATH")联系客服
