腳本備查：

cd "$(brew --repo)"

git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile

source ~/.bash_profile

前兩步實際上就是去/usr/local/Homebrew目錄下把brew和brew-core的git路徑給換了，最后一步是二進制

源需要修改bashprofile文件改變量。

完后再執行一次brew update
