我认为OP正在寻找一个简单的，类似windows的解决方案。

给你:

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

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。

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。

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

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
