除了建议的方法之外，还有一件事需要注意，至少在OS X 10.5 (Leopard)中，launchd.conf中设置的变量将与.profile中的设置合并。我认为这可能对~/. macosx /environment中的设置有效。plist也是，但我还没有验证。

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。

在Mac OS上设置PATH环境变量

打开终端程序(默认在应用程序/实用程序文件夹中)。运行以下命令

touch ~/.bash_profile; open ~/.bash_profile

这将在默认文本编辑器中打开文件。

以Android SDK为例:

你需要添加路径到你的Android SDK平台工具和工具目录。在我的例子中，我将使用“/Development/android-sdk-macosx”作为SDK的安装目录。增加如下一行:

export PATH=${PATH}:/Development/android-sdk-macosx/platform-tools:/Development/android-sdk-macosx/tools

保存文件并退出文本编辑器。执行.bash_profile更新PATH:

source ~/.bash_profile

现在，每次你打开终端程序，你的路径将包括Android SDK。

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.

对于Bash，尝试将环境变量添加到文件/etc/profile中，以使它们对所有用户可用。不需要重新启动，只需启动一个新的终端会话。

做的事: vim ~ / . bash_profile 文件可能不存在(如果不存在，您可以直接创建它)。 输入并保存文件: 导出路径= $路径:YOUR_PATH_HERE 运行 源~ / . bash_profile
