/usr/local/bin/ruby ~/brew_install 安装brew，在安装的时候，会卡在安装homebrewcore 界面，
此时，直接git clone homebrewcore到homebrew里面 sudo git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
或者清华大学镜像： sudo git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
大功告成。
