Updating Homebrew... 长时间不动解决方法

确保你已安装Homebrew

依次输入下面的命令（注意：不要管重置部分的命令，这里原作者贴出来、我也贴出来是以防需要重置的时候有参考操作命令）

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

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