我的个人实践是.bash_profile。我在这里添加路径并附加到Path变量，

GOPATH=/usr/local/go/bin/
MYSQLPATH=/usr/local/opt/mysql@5.6/bin

PATH=$PATH:$GOPATH:$MYSQLPATH

之后，我可以有个人的路径通过echo$ GOPATH, echo$MYSQLPATH或所有通过echo$ Path。

我认为OP正在寻找一个简单的，类似windows的解决方案。

虽然这里的答案并不是“错误的”，但我还要补充一点:永远不要在OS X中改变影响“所有进程”的环境变量，甚至在shell之外，也不要影响给定用户交互运行的所有进程。

In my experience, global changes to environment variables like PATH for all processes are even more likely to break things on OS X than on Windows. Reason being, lots of OS X applications and other software (including, perhaps especially, components of the OS itself) rely on UNIX command-line tools under the hood, and assume the behavior of the versions of these tools provided with the system, and don't necessarily use absolute paths when doing so (similar comments apply to dynamically-loaded libraries and DYLD_* environment variables). Consider, for instance, that the highest-rated answers to various Stack Overflow questions about replacing OS X-supplied versions of interpreters like Python and Ruby generally say "don't do this."

OS X is really no different than other UNIX-like operating systems (e.g., Linux, FreeBSD, and Solaris) in this respect; the most likely reason Apple doesn't provide an easy way to do this is because it breaks things. To the extent Windows isn't as prone to these problems, it's due to two things: (1) Windows software doesn't tend to rely on command-line tools to the extent that UNIX software does, and (2) Microsoft has had such an extensive history of both "DLL hell" and security problems caused by changes that affect all processes that they've changed the behavior of dynamic loading in newer Windows versions to limit the impact of "global" configuration options like PATH.

不管“蹩脚”与否，如果您将这些更改限制在较小的范围内，您将拥有一个更加稳定的系统。

简单又快速地做了这个。首先创建一个~/。Bash_profile来自终端:

touch .bash_profile

then

open -a TextEdit.app .bash_profile

add

export TOMCAT_HOME=/Library/Tomcat/Home

保存文档，您就完成了。

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.
