之后就可以卸载重装了

另外如果brew速度慢，考虑更换为中国科大或者清华大学的下载源

替换brew.git:

$ cd "$(brew --repo)"

中国科大:

$ git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

清华大学:

$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

替换homebrew-core.git:

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

中国科大:

$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

清华大学:

$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

替换homebrew-bottles:

中国科大:

$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile

清华大学:

$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile

应用生效:

$ brew update

如果需要重置为官方源， 使用如下方法

重置brew.git:

$ cd "$(brew --repo)"
$ git remote set-url origin https://github.com/Homebrew/brew.git

重置homebrew-core.git:

$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
$ git remote set-url origin https://github.com/Homebrew/homebrew-core.git
