Related to my previous question: Pymacs not starting on Emacs24 Carbon
Ropemacs won't load, since emacs isn't seeing the correct site-packages directory (see the previous question for example output).
I'm using Snow Leopard, with the dev version of emacs24 installed through homebrew.
$ emacs --version
GNU Emacs 24.0.93.1
Python is also installed through homebrew, and preferred by setting it at the front of my path.
$ python --version
Python 2.7.2
I use zsh as my login shell.
If I type M-! python --version into emacs, it returns Python 2.6.1, even though in my shell, /usr/local/bin is ahead of /usr/bin in my PATH. Indeed, emacs thinks my path is "reversed", in the sense that the default Python framework is ahead of my preferred python. I think this may be caused by path_helper.
zsh PATH:
$ echo $PATH
/Users/jrhorn424/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin: *snip*
emacs PATH:
M-! echo $PATH [RET]
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin: *snip*
I have the zsh path copied into ~/.MacOSX/environment.plist, but that doesn't prevent /usr/bin from prefixing in emacs.
Possibly related: Emacs is ignoring my path when it runs a compile command
I've implemented that solution, which is included in this list of solutions to the PATH problem, but I'm still getting the results above. Perhaps these solutions are a bit dated?
Telling me to upgrade to Lion, if you can convince me it will solve my issue, is OK, but I would prefer to stay with Snow Leopard for now.
回答1:
Edit /etc/path (as an administrator) and move the line /usr/local/bin to the top of the file.
