注:该镜像是 Homebrew/Linuxbrew 的 formula 索引的镜像（即 brew update 时所更新内容）。本镜像站同时提供相应的二进制预编译包的镜像，请参考 Homebrew bottles 镜像使用帮助 和 Linuxbrew bottles 镜像使用帮助。
官网上提供的安装脚本是 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" ，为了加速克隆的速度，你需要下载 https://raw.githubusercontent.com/Homebrew/install/master/install.sh 并编辑其中的：
BREW_REPO="https://github.com/Homebrew/brew"
# 变成：
BREW_REPO="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git"
接着，运行 install.sh 以安装 Homebrew：
HOMEBREW_CORE_GIT_REMOTE=https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git bash install.sh
这样在首次安装的时候也可以使用镜像。
