使用科大源安装 Homebrew / Linuxbrew
首先在命令行运行如下几条命令设置环境变量：
export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.ustc.edu.cn/brew.git"
export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.ustc.edu.cn/homebrew-core.git"
export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.ustc.edu.cn/homebrew-bottles"
之后在命令行运行 Homebrew 安装脚本：
/bin/bash -c "$(curl -fsSL https://github.com/Homebrew/install/raw/HEAD/install.sh)"
