在 mac 下使用 brew 安装包的时候，最后一行会报错：
fatal: not in a git directory
Error: Command failed with exit 128: git
导致包安装不成功，解决办法：
brew -v
绿色框就是提示你需要做的，输入
git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-core
git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-cask
再次使用 brew install xxx 安装包，可以安装成功啦！
