set x=y is the Windows CMD syntax to set an environment variable , just as x=y;export x or export x=y or setenv xy is on most Unix shells. set x=y是Windows CMD语法来设置环境变量 ，就像x=y;export x大多数Unix shell上都使用x=y;export x或export x=y或setenv xy 。

You can pre-set a (semi)permanent env var in Windows from ControlPanel / System (or ThisPC rightclick Properties), AdvancedSystemSettings, Advanced tab, EnvironmentVariables button. 您可以在Windows中通过ControlPanel /系统（或ThisPC右键单击“属性”），“ AdvancedSystemSettings”，“高级”选项卡，“ EnvironmentVariables”按钮预先设置一个（半）永久环境。 Or from CMD with the SETX command; 或使用SETX命令从CMD获得； SETX /? for help or http://ss64.com/nt/setx.html . 寻求帮助或http://ss64.com/nt/setx.html 。 (Or directly in the registry, but if you have enough skill to use regedit safely you wouldn't ask this Q.) （或者直接在注册表中，但是如果您有足够的技能安全地使用regedit，则不会问这个问题。）
