Mac下设计全局环境变量

MAC 操作系统的全局环境变量不像其他linux的设置方式，mac下需要用launchd launchctl来进行设置。 

 

Here are the steps necessary to setup Environment Variables in Mountain Lion:

• Open a Terminal Window.
• Use the command ‘sudo nano /etc/launchd.conf’.
  
• Enter your password.
• Add the environment variables using the following syntax:

setenv NAME_OF_VARIABLE valueOfTheVariable

• Press ‘Ctrl + o’ to save the file
• Press enter to accept the name of the file
• Press ‘Ctrl + x’ to exit the editor.

比较奇怪的是， 

 

OS X Yosemite 10.10 又不用这个文件了， 又改回去用 /etc/profile 文件了。

修改profile文件： 
#vi /etc/profile 
在里面加入:
export PATH="$PATH:/opt/au1200_rm/build_tools/bin"

 

想立即生效请运行：

#source /etc/profile

不报错则成功。
