如上终端中 code 所示，执行如下语句
首先，更换有效的镜像地址；

git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1

其次，前往至 homebrew-core 将其当前的镜像地址也更为有效的地址；

cd "$(brew --repo)" 
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" 
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

再其次，将如上配置文件内容更替后，重新执行更新；

brew update

最后，执行完如上操作后，终端显示如下字样内容即可。

Already up-to-date.
