我无法在我的mac上安装hyper kit。我正在从终端发出brew install hyperkit命令。下面是日志结果

Kjango-MacBook-Air:~ kanan$ brew install hyperkit

hyperkit: A full installation of Xcode.app 9.0 is required to compile
this software. Installing just the Command Line Tools is not sufficient.

Xcode can be installed from the App Store.
Error: An unsatisfied requirement failed this build.

如果你能帮我解决，我将不胜感激。
谢谢
