Emacs在运行编译命令时忽略了我的路径 [英] Emacs is ignoring my path when it runs a compile command

问题描述

我正在尝试获得一个编译命令（耙子黄瓜）在Mac OS X系统上运行特定的ruby版本，我使用rvm目前在终端中执行此操作。我的〜/ .MacOSX / environment.plist里面有正确的路径，但emacs坚持在这个路径前面，因此使它无用。我也尝试过：

 （when（equal system-type'darwin）
（setenvPATH concat/Users/fearoffish/.rvm/bin:/Users/fearoffish/.rvm/rubies/ruby-1.8.7-p249/bin:/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249/ bin：/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249%global/bin：/Users/fearoffish/.rvm/bin））
（push/Users/fearoffish/.rvm / binexec-path）
（push/Users/fearoffish/.rvm/rubies/ruby-1.8.7-p249/binexec-path）
（push/ Users / fearoffish / exec-path）
（推/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249%global/binexec-路径）
（推/Users/fearoffish/.rvm/binexec-path））
  

这是emacs初学者绝望的尝试得到我想要的。它仍然在它的前面，所以我的路径最终是：

  / usr / bin ：/ bin中：/ usr / sbin目录：/ sbin目录：在/ usr / local / bin目录：在/ usr / X11 / bin中：/Users/fearoffish/.rvm/bin：/Users/fearoffish/.rvm/rubies/ruby-1.8。 7-p249 / bin：/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249/bin：/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249%global/bin 
  

我不希望/ usr / bin和其他人在前面，我想要我的路径首先和emacs前面的路径是结束，我认为这将解决我的问题。

我通过简单地打开Aquamacs并运行 meta-x编译然后 echo $ PATH 。

任何想法？ p>

解决方案

sanityinc解决方案的一个小的修改（在上面的评论中找不到一个方法来输入）我使用 -l <​​/ code>选项到shell来强制登录shell（它读取 .profile 或 .bash_profile ），而不是一个交互式shell（只读 .bashrc ）。


我在返回的路径上做一些字符串修剪（视检查显示换行）潜行。

修改后的代码：

 （defun set-exec-path-from-shell-PATH（）
 let（（path-from-shell 
（replace-regexp-in-string[[：space：] \\\
] * $
（shell-command-to-string$ SHELL -l -c'echo $ PATH'））））
（setenvPATHfrom-shell）
（setq exec-path（split-string path-from-shell path-分隔符））））
（等于系统类型'darwin）（set-exec-path-from-shell-PATH））
  

I'm trying to get a compile command (rake cucumber) to run with a specific ruby version on my Mac OS X system, I use rvm to do this currently in the terminal. My ~/.MacOSX/environment.plist has the correct path in it, but emacs insists on prepending to this path and therefore making it useless. I've also tried:

(when (equal system-type 'darwin)
  (setenv "PATH" (concat "/Users/fearoffish/.rvm/bin:/Users/fearoffish/.rvm/rubies/ruby-1.8.7-p249/bin:/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249/bin:/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249%global/bin:/Users/fearoffish/.rvm/bin"))
  (push "/Users/fearoffish/.rvm/bin" exec-path)
  (push "/Users/fearoffish/.rvm/rubies/ruby-1.8.7-p249/bin" exec-path)
  (push "/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249/bin" exec-path)
  (push "/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249%global/bin" exec-path)
  (push "/Users/fearoffish/.rvm/bin" exec-path))

It was the desperate attempt of an emacs beginner to get what I wanted. It still prepends in front of it, so my path ends up being:

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Users/fearoffish/.rvm/bin:/Users/fearoffish/.rvm/rubies/ruby-1.8.7-p249/bin:/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249/bin:/Users/fearoffish/.rvm/gems/ruby-1.8.7-p249%global/bin

I don't want /usr/bin and others prepending, I want my path first and the emacs prepended path to be at the end, I reckon this would fix my problem.

I test this by simply opening Aquamacs and running meta-x compile and then echo $PATH.

Any ideas?

解决方案

A small modification to the solution by sanityinc (couldn't find a way to enter it in the comments above -- is that just me?)

• I use -l option to the shell to force a login shell (which reads .profile or .bash_profile), rather than an interactive shell (which only reads .bashrc).
• I do some string trimming on the returned path (as inspection shows a newline sneaking in).

Modified code:

(defun set-exec-path-from-shell-PATH ()
  (let ((path-from-shell 
      (replace-regexp-in-string "[[:space:]\n]*$" "" 
        (shell-command-to-string "$SHELL -l -c 'echo $PATH'"))))
    (setenv "PATH" path-from-shell)
    (setq exec-path (split-string path-from-shell path-separator))))
(when (equal system-type 'darwin) (set-exec-path-from-shell-PATH))
