从macOS 10.12.6 (Sierra)开始，这个方法似乎已经停止在Apache httpd上工作(对于系统和launchctl配置的用户选项)。其他项目似乎没有受到影响。可以想象，这是httpd中的一个bug。

原来的答案

这涉及到OS X 10.10+(特别是10.11+由于无根模式，其中/usr/bin不再可写)。

我在很多地方读到过，使用launchctl setenv PATH <new PATH >来设置PATH变量由于OS X中的一个错误而不起作用(从个人经验来看似乎是正确的)。我发现还有另一种方法可以为非shell启动的应用程序设置PATH:

sudo launchctl config user path <new path>

这个选项记录在launchctl手册页中:

config system | user parameter value Sets persistent configuration information for launchd(8) domains. Only the system domain and user domains may be configured. The location of the persistent storage is an implementation detail, and changes to that storage should only be made through this subcommand. A reboot is required for changes made through this subcommand to take effect. [...] path Sets the PATH environment variable for all services within the target domain to the string value. The string value should conform to the format outlined for the PATH environment variable in environ(7). Note that if a service specifies its own PATH, the service-specific environment variable will take precedence. NOTE: This facility cannot be used to set general environment variables for all services within the domain. It is intentionally scoped to the PATH environment vari- able and nothing else for security reasons.

我已经确认这与从Finder(使用getenv获取PATH)开始的GUI应用程序一起工作。 请注意，您只需要这样做一次，并且更改将在重新启动时保持不变。

很简单:

编辑~ /。对变量进行配置并按如下方式放置

$ vim ~/.profile

在文件中放置:

MY_ENV_VAR =值

保存(:wq) 重启终端(退出并重新打开) 确保这一切都没问题:

$MY_ENV_VAR 美元的价值

布鲁诺正在正确的轨道上。我已经做了大量的研究，如果你想设置在所有GUI应用程序中可用的变量，你唯一的选择是/etc/launchd.conf。

请注意环境。plist不适用于通过Spotlight启动的应用程序。这是由史蒂夫·塞克斯顿记录的。

Open a terminal prompt Type sudo vi /etc/launchd.conf (note: this file might not yet exist) Put contents like the following into the file # Set environment variables here so they are available globally to all apps # (and Terminal), including those launched via Spotlight. # # After editing this file run the following command from the terminal to update # environment variables globally without needing to reboot. # NOTE: You will still need to restart the relevant application (including # Terminal) to pick up the changes! # grep -E "^setenv" /etc/launchd.conf | xargs -t -L 1 launchctl # # See http://www.digitaledgesw.com/node/31 # and http://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x/ # # Note that you must hardcode the paths below, don't use environment variables. # You also need to surround multiple values in quotes, see MAVEN_OPTS example below. # setenv JAVA_VERSION 1.6 setenv JAVA_HOME /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home setenv GROOVY_HOME /Applications/Dev/groovy setenv GRAILS_HOME /Applications/Dev/grails setenv NEXUS_HOME /Applications/Dev/nexus/nexus-webapp setenv JRUBY_HOME /Applications/Dev/jruby setenv ANT_HOME /Applications/Dev/apache-ant setenv ANT_OPTS -Xmx512M setenv MAVEN_OPTS "-Xmx1024M -XX:MaxPermSize=512m" setenv M2_HOME /Applications/Dev/apache-maven setenv JMETER_HOME /Applications/Dev/jakarta-jmeter Save your changes in vi and reboot your Mac. Or use the grep/xargs command which is shown in the code comment above. Prove that your variables are working by opening a Terminal window and typing export and you should see your new variables. These will also be available in IntelliJ IDEA and other GUI applications you launch via Spotlight.

iOS上的所有神奇之处都是使用source和文件，在这里导出环境变量。

例如:

你可以像这样创建一个文件:

export bim=fooo
export bom=bar

保存为bimbom。Env，然后做source ./bimbom.ev。 Voilá，你有你的环境变量。

检查它们:

echo $bim

/etc/launchd.conf在OS X v10.10 (Yosemite)、OS X v10.11 (El Capitan)、macOS v10.12 (Sierra)或macOS v10.13 (High Sierra)中不使用。

从launchctl手册页:

/etc/launchd.conf file is no longer consulted for subcommands to run during early boot time;
this functionality was removed for security considerations.

这个Ask Different answer中描述的方法适用于我(重启后):从Dock或Spotlight启动的应用程序继承了我在~/Library/LaunchAgents/my.startup.plist中设置的环境变量。(在我的例子中，我需要将LANG设置为en_US。UTF-8，用于Sublime Text插件。)

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
