MacOS Homebrew下载替换国内镜像源
共需要替换几个部分的镜像源：homebrew、homebrew-core、homebrew-cask、homebrew-bottles。
1. 查看地址：
echo $(brew --repo)
echo $(brew --repo homebrew/core)
echo $(brew --repo homebrew/cask)
2. 修改homebrew、homebrew-core、homebrew-cask地址：
$ git -C "$(brew --repo)" remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
$ git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-cask.git
3. 修改homebrew-bottles地址：
先查看shell版本
echo $SHELL
如果输出是/bin/bash，执行：
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile
如果输出是/bin/zsh，执行：
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc
$ source ~/.zshrc
如果需要重置回地址为官方：
$ git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew.git
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://github.com/Homebrew/homebrew-core
$ git -C "$(brew --repo homebrew/cask)" remote set-url origin https://github.com/Homebrew/homebrew-cask
