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.

这里有一个非常简单的方法来做你想做的事情。在我的例子中，它是让Gradle工作(Android Studio)。

打开终端。 执行如下命令: Sudo nano /etc/paths或Sudo vim /etc/paths 在提示时输入密码。 转到文件底部，输入要添加的路径。 点击Control + X退出。 输入“Y”保存修改后的缓冲区。 打开一个新的终端窗口，然后输入: 回声路径美元

您应该看到新路径被追加到path的末尾。

我从这篇文章中得到了这些细节:

添加到Mac OS X 10.8 Mountain Lion及以上版本的PATH中

这很简单。编辑文件.profile (vi, nano, Sublime Text或其他文本编辑器)文件。你可以在~/目录(用户目录)中找到它，并像这样设置:

export MY_VAR=[your value here]

Java home的示例:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/current

保存它并返回到终端。

你可以用:

source .profile

或者关闭并打开终端窗口。

$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。

2月2022日(MacOs 12+)

这里的解决方案应该在重新启动或应用程序重新启动后工作。

CLI

打开所选配置文件的CLI。

为bash打开~/.bash_profile 为zsh打开~/.zshrc

添加(或替换)

export varName=varValue 

(如果varValue中有空格-将其包装成")

确保重新启动命令行应用程序。

GUI

完成CLI步骤。 确保GUI应用程序关闭。 从命令行打开GUI应用程序。例如:

open /Applications/Sourcetree.app

(你也可以在.zshrc文件中使用这个命令的别名)

原则

Mac没有为所有上下文设置环境变量的配置选项。 避免更改用户配置文件之外的任何内容。

已经不管用了

(MacOS 12.1+) 编辑/etc/launchd.conf 带有plist后缀的XML文件

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.
