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。

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。

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。

嗯，我不确定/etc/paths和~/. macosx /environment。plist文件。那些是新的。

但是使用Bash时，您应该知道每次新的shell调用都会执行.bashrc 并且.bash_profile只在启动时执行一次。

我不知道在Mac OS x上这种情况发生的频率有多高。我想随着windows系统启动一切，这种区别已经消失了。

就我个人而言，我通过创建一个.bashrc文件来消除困惑，其中包含我需要的所有内容，然后执行:

ln -s .bashrc .bash_profile
