使用 brew config 检查brew的配置项

我的配置项中core tap有配置项缺失，所以brew无法找到包

Core tap ORIGIN: https://github.com/Homebrew/homebrew-core
Core tap HEAD: (none)
Core tap last commit: never
Core tap branch: HEAD

执行以下命令，删除原有的homebrew-core文件夹，重新创建

rm -rf /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
brew tap homebrew/core

修复core tap的配置项后：

Core tap ORIGIN: https://github.com/Homebrew/homebrew-core
Core tap HEAD: 78dbff03e5f3a0c9f4a341788e563f060064540e
Core tap last commit: 4 minutes ago
Core tap branch: master

此时重新 brew install git成功啦 👏🏻

一开始还遇到有mac使用brew的权限问题，根据命令行的提示用sudo给予一定的配置后就可以使用brew了
