又要很長時間等待，不能再忍了
換國內的源來加速，例如清華的（https://mirrors.tuna.tsinghua.edu.cn/help/homebrew/）
執行如下命令
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
brew update
完成安裝
