macOS更新后Git无法正常运行（xcrun：错误：无效的活动开发人员路径（/ Library / Developer / CommandLineTools）

问题：

Last night (November 2018) I updated to macOS Mojave, (this will probably work for Catalina too) 昨晚（2018年11月）我更新到了macOS Mojave，（这可能也适用于Catalina）

This morning I navigated to my work's code base in Command line on my MacBook pro, 今天早上，我在MacBook Pro的命令行中导航到工作的代码库，

typed in "git status" in the repo and received the error: 在仓库中输入“ git status”并收到错误：

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
