1.设置环境变量
export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git"
export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git"
export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles"
2.从镜像下载homebrew
git clone --depth=1 https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/install.git
cd install
/bin/bash brew-install/install.sh
处理完毕，删掉install文件夹
3.到这里brew就安装好了，但是推荐做以下步骤
export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git"
for tap in core cask{,-fonts,-drivers,-versions} command-not-found; do
brew tap --custom-remote --force-auto-update "homebrew/${tap}" "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-${tap}.git"
done
brew update
test -r ~/.bash_profile && echo 'export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git"' >> ~/.bash_profile # bash
test -r ~/.bash_profile && echo 'export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git"' >> ~/.bash_profile
