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。

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.

不要期望~/.launchd.conf能够工作

launchctl的手册页说它从来没有工作过:

已弃用和删除的功能 Launchctl不再具有交互模式，也不再接受来自stdin的命令。/etc/launchd.conf文件不再用于在早期启动时运行子命令;出于安全考虑，该功能已被删除。虽然有文档表明在设置用户会话之前会查询$HOME/.launchd.conf，但这个功能从未实现过。

如何为Spotlight启动的新进程设置环境(不需要重新启动)

您可以使用launchctl setenv设置launchd(以及从Spotlight开始的任何东西)所使用的环境。例如，设置路径:

launchctl setenv PATH /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin

或者如果你想在。bashrc或类似文件中设置你的路径，那么在launchd中镜像它:

PATH=/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin
launchctl setenv PATH $PATH

没有必要重新启动，但如果你想让应用程序接受改变的环境，就需要重新启动应用程序。

这包括已经在终端下运行的任何shell。如果你在那里，你可以更直接地设置环境，例如export PATH=/opt/local/bin:/opt/local/sbin:$PATH for bash或zsh。

重启后如何保持更改

新方法(自10.10 Yosemite起)

使用launchctl config用户路径/bin:/usr/bin:/mystuff。更多信息请参见man launchctl。

以前的方法

这个答案顶部的launchctl手册页引用说，出于安全原因，这里描述的特性(在引导时读取/etc/launchd.conf)被删除了，因此ymmv. conf。

为了在重启后保持更改，你可以在/etc/launchd.conf中设置环境变量，如下所示:

setenv PATH /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin

重启时自动执行Launchd.conf。

如果你想让这些改变现在生效，你应该使用这个命令重新处理launchd.conf(感谢@mklement的提示!)

egrep -v '^\s*#' /etc/launchd.conf | launchctl

你可以通过命令man launchctl找到更多关于launchctl以及它如何加载launchd.conf的信息。

直到和包括OS X v10.7 (Lion)，你可以设置它们:

~/.MacOSX/environment.plist

See:

https://developer.apple.com/legacy/library/qa/qa1067/_index.html https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/EnvironmentVars.html

对于终端中的PATH，您应该能够在.bash_profile或.profile中设置(尽管您可能必须创建它)

对于OS X v10.8 (Mountain Lion)及以上版本，您需要使用launchd和launchctl。

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。

在处理时，基本上有两个问题需要解决 第一个是在调用程序时 来自Spotlight (Mac右侧的放大镜图标) 菜单/状态栏)，第二个是从Dock调用程序。 从终端应用程序/实用程序调用程序非常简单 因为它从标准shell位置读取环境 (~ /。简介~ /。bash_profile、~ /。bashrc,(等等)。

当从Dock调用程序时，使用~/.MacOSX/environment.plist <dict>元素包含序列 <键>键< /关键> <字符串> < /字符串>价值元素。

当从Spotlight调用程序时，确保launchd已经启动 设置所需的所有键/值设置。

To solve both problems simultaneously, I use a login item (set via the System Preferences tool) on my User account. The login item is a bash script that invokes an Emacs lisp function although one can of course use their favorite scripting tool to accomplish the same thing. This approach has the added benefit that it works at any time and does not require a reboot, i.e. one can edit ~/.profile, run the login item in some shell and have the changes visible for newly invoked programs, from either the Dock or Spotlight.

细节:

登录项:~/bin/macosx-startup

#!/bin/bash
bash -l -c "/Applications/Emacs.app/Contents/MacOS/Emacs --batch -l ~/lib/emacs/elisp/macosx/environment-support.el -f generate-environment"

Emacs的lisp功能:~/lib/ Emacs /elisp/macosx/ environment -support.el

;;; Provide support for the environment on Mac OS X

(defun generate-environment ()
  "Dump the current environment into the ~/.MacOSX/environment.plist file."
  ;; The system environment is found in the global variable:
  ;; 'initial-environment' as a list of "KEY=VALUE" pairs.
  (let ((list initial-environment)
        pair start command key value)
    ;; clear out the current environment settings
    (find-file "~/.MacOSX/environment.plist")
    (goto-char (point-min))
    (setq start (search-forward "<dict>\n"))
    (search-forward "</dict>")
    (beginning-of-line)
    (delete-region start (point))
    (while list
      (setq pair (split-string (car list) "=")
            list (cdr list))
      (setq key (nth 0 pair)
            value (nth 1 pair))
      (insert "  <key>" key "</key>\n")
      (insert "  <string>" value "</string>\n")

      ;; Enable this variable in launchd
      (setq command (format "launchctl setenv %s \"%s\"" key value))
      (shell-command command))
    ;; Save the buffer.
    (save-buffer)))

注意:这个解决方案是在我添加我的解决方案之前的一个混合体，特别是由Matt Curtis提供的解决方案，但我故意试图保持我的~/。bash_profile独立于内容平台，并将launchd环境(Mac专用工具)的设置放到单独的脚本中。
