I'm installing 'THERMUS: A Thermal Model Package for ROOT' on macOs Mojave. One of the steps is (after unzipping) the following: "Set an environment variable `THERMUS' to point at the top-level directory containing the THERMUS code". I really don't know what to do. I've seen the other post on stackoverflow: 'no rule to make target' with no reason, but, as I am a beginner, I really don't understand how I should set it. Please help me

推荐答案

要在Mac OSX上设置环境变量，请首先打开一个终端窗口. 如果要设置环境变量以从命令行运行作业，请使用以下命令:

To set an environment variable on Mac OSX, first open a terminal window. If you are setting the environment variable to run jobs from the command line, use the following command:

export variable=value

其中，变量是环境变量的名称(例如，程序员)，而值是要分配给该变量的值(例如，/opt/programmer/suites2013).您可以找出使用env命令设置了哪些环境变量.

where variable is the name of the environment variable (such as programmer) and value is the value you want to assign to the variable, (such as /opt/programmer/suites2013). You can find out which environment variables have been set with the env command.

如果要全局设置环境变量以与应用程序一起使用，请使用下面给出的命令.这些命令设置的环境变量可被任何外壳程序或应用程序继承. OS X 10.10

If you are setting the environment variable globally to use with applications, use the commands given below. The environment variables set by these commands are inherited by any shell or application. OS X 10.10

# To set an environment variable, enter the following command:
launchctl setenv variable "value"

# To find out if an environment variable is set, use the following command:
launchctl getenv variable

# To clear an environment variable, use the following command:
launchctl unsetenv variable
