Emacs is ignoring my path when it runs a compile command

Question

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/

Answer 1

I find the environment.plist scheme on Macs pretty ugly, so I use the following snippet, which assumes you want Emacs to use the same PATH that you see in your Terminal.app:

(defun set-exec-path-from-shell-PATH ()
  (let ((path-from-shell (shell-command-to-string "$SHELL -i -c 'echo $PATH'")))
    (setenv "PATH" path-from-shell)
    (setq exec-path (split-string path-from-shell path-separator))))

(This works for me in Emacs 23; haven't tried it in other versions, but I'd expect it to work.)
