homebrew 升级的命令很简单
brew update-reset
但是在升级过程中会因为墙引发 time-out，主要事 brew 默认都是 github 的源
主要修改下面几块
# 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-cask.git:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-cask"
$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git
# 替换homebrew-cask-version.git:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-cask-version"
$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask-versions.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
如果你又想换回官方的源
# 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
#其余的同理
