在OS X中修改环境变量如PATH的正确方法是什么?

我看了谷歌一点,找到了三个不同的文件进行编辑:

/etc/paths ~ / . profile ~ / tcshrc

我甚至没有这些文件中的一些,我很确定.tcshrc是错误的,因为OS X现在使用bash。这些变量,特别是PATH,定义在哪里?

我运行的是OS X v10.5 (Leopard)。


当前回答

对于单个用户修改,使用~/。你列出的人的简介。下面的链接解释了Bash何时读取不同的文件。

如果你想为gui应用程序设置环境变量,你需要~/. macosx /environment。plist文件

其他回答

任何Bash启动文件—~/。bashrc,(~ /。bash_profile、~ / . profile。还有一些奇怪的文件,名为~/. macosx /environment。用于GUI应用程序中的环境变量。

$PATH变量也受制于path_helper,它反过来利用/etc/paths文件和/etc/paths.d中的文件

更详细的描述可以在PATH和Leopard(2008-11)的其他环境问题中找到。

就像Matt Curtis给出的答案一样,我通过launchctl设置环境变量,但我将它包装在一个名为export的函数中,因此每当我像在.bash_profile中一样导出一个变量时,它也由launchctl设置。我是这样做的:

My .bash_profile consists solely of one line, (This is just personal preference.) source .bashrc My .bashrc has this: function export() { builtin export "$@" if [[ ${#@} -eq 1 && "${@//[^=]/}" ]] then launchctl setenv "${@%%=*}" "${@#*=}" elif [[ ! "${@//[^ ]/}" ]] then launchctl setenv "${@}" "${!@}" fi } export -f export The above will overload the Bash builtin "export" and will export everything normally (you'll notice I export "export" with it!), then properly set them for OS X app environments via launchctl, whether you use any of the following: export LC_CTYPE=en_US.UTF-8 # ~$ launchctl getenv LC_CTYPE # en_US.UTF-8 PATH="/usr/local/bin:${PATH}" PATH="/usr/local/opt/coreutils/libexec/gnubin:${PATH}" export PATH # ~$ launchctl getenv PATH # /usr/local/opt/coreutils/libexec/gnubin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin export CXX_FLAGS="-mmacosx-version-min=10.9" # ~$ launchctl getenv CXX_FLAGS # -mmacosx-version-min=10.9 This way I don't have to send every variable to launchctl every time, and I can just have my .bash_profile / .bashrc set up the way I want. Open a terminal window, check out your environment variables you're interested in with launchctl getenv myVar, change something in your .bash_profile/.bashrc, close the terminal window and re-open it, check the variable again with launchctl, and voilá, it's changed. Again, like the other solutions for the post-Mountain Lion world, for any new environment variables to be available for apps, you need to launch or re-launch them after the change.

另一个免费、开源的Mac OS X v10.8 (Mountain Lion)首选项窗格/环境。plist解决方案是EnvPane。

EnvPane的源代码可在GitHub。EnvPane看起来具有与rcenvirenvironment相当的功能,然而,它似乎可以立即更新其存储的变量,即不需要重新启动或登录,这是受欢迎的。

如开发商所述:

EnvPane is a preference pane for Mac OS X 10.8 (Mountain Lion) that lets you set environment variables for all programs in both graphical and terminal sessions. Not only does it restore support for ~/.MacOSX/environment.plist in Mountain Lion, it also publishes your changes to the environment immediately, without the need to log out and back in. <SNIP> EnvPane includes (and automatically installs) a launchd agent that runs 1) early after login and 2) whenever the ~/.MacOSX/environment.plist changes. The agent reads ~/.MacOSX/environment.plist and exports the environment variables from that file to the current user's launchd instance via the same API that is used by launchctl setenv and launchctl unsetenv.

免责声明:我与开发者或他/她的项目没有任何关系。

附注:我喜欢这个名字(听起来像“Ends Pain”)。

/etc/launchd.conf在OS X v10.10 (Yosemite)、OS X v10.11 (El Capitan)、macOS v10.12 (Sierra)或macOS v10.13 (High Sierra)中不使用。


从launchctl手册页:

/etc/launchd.conf file is no longer consulted for subcommands to run during early boot time;
this functionality was removed for security considerations.

这个Ask Different answer中描述的方法适用于我(重启后):从Dock或Spotlight启动的应用程序继承了我在~/Library/LaunchAgents/my.startup.plist中设置的环境变量。(在我的例子中,我需要将LANG设置为en_US。UTF-8,用于Sublime Text插件。)
