Mac
1. brew
我们使用linux下有yum，mac相应的是brew，直接使用中科大源安装brew
/usr/bin/ruby -e "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install)"
# 换源
# $ 指返回 brew --repo 的结果
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" // ? homebrew-cask
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
