brew安装失败解决方案

根据brew官网安装失败，网上找了一圈，自己总结了下方法，mark一下

1.直接克隆项https://github.com/Homebrew/brew

2.备注项目中bin目录到环境变量

3.brew doctor验证

4.修改brew的源为国内的源

-cd "$(brew --repo)"

-git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

-cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

-git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
