我正在尝试在我的机器上安装 xmonad,我现在在说明中(http://www.haskell.org/haskellwiki/Xmonad/Using_xmonad_on_Apple_OSX#Installing_xmonad)
2.2 Configuring Your .profile
Insert the following into your ~/.profile
export PATH=$PATH:~/.cabal/bin:/usr/local/bin
export USERWM=`which xmonad`
Much of this isn't needed until later, but it's good to get it out the way now.
2.2.1 Installing Cabal
我了解发生了什么,export PATH=$PATH:~/.cabal/bin:/usr/local/bin
但有人可以解释一下 1. USERWM 全局变量是什么以及分配给它的确切含义是什么?(我假设“which xmonad”不是字面意思)。它是xmonad的版本号吗?还有什么?
