Mac升级Mojave后使用出现xcrun：error错误

错误信息

使用 Homebrew 时发现出错了，提示:

Updating Homebrew...
==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Error: Failure while executing; `git config --local --replace-all homebrew.analyticsmessage true` exited with 1.

解决办法

可能原因：mac 系统升级后，自动卸载 xcode-select，引起 Git 不能正常工作引起的。

解决方法就是：

sudo xcode-select --install
