homebrew 升級的命令很簡單

brew update-reset

但是在升級過程中會因為墻引發(fā) time-out，主要事 brew 默認(rèn)都是 github 的源

主要修改下面幾塊

# 替換brew.git:
$ cd "$(brew --repo)"
# 中國科大:
$ git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
# 清華大學(xué):
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

# 替換homebrew-core.git:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
# 中國科大:
$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
# 清華大學(xué):
$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

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

# 替換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

# 替換homebrew-bottles:
# 中國科大:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile
# 清華大學(xué):
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile

如果你又想換回官方的源

# 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
