更新源的选择

homebrew默认官方的更新源都是存放在GitHub上的，这也是中国大陆用户访问缓慢的原因，一般来说我们会更倾向选择国内提供的更新源，试用了几个源之后在此推荐中国科大提供的更新源。

替换更新源

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

# 应用生效:
$ brew update

或者

# 替换各个源
$ git -C "$(brew --repo)" remote set-url origin https://mirrors.ustc.edu.cn/brew.git
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
$ git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

# zsh 替换 brew bintray 镜像
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
$ source ~/.zshrc

# bash 替换 brew bintray 镜像
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile

# 刷新源
$ brew update

如果你之前折腾过不少导致你的Homebrew有点问题，那么可以尝试使用如下方案：

# 诊断Homebrew的问题:
$ brew doctor

# 重置brew.git设置:
$ cd "$(brew --repo)"
$ git fetch
$ git reset --hard origin/master

# homebrew-core.git同理:
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
$ git fetch
$ git reset --hard origin/master

# 应用生效:
$ brew update  

清华源

# 替换各个源
$ git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
$ git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git

# zsh 替换 brew bintray 镜像
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.zshrc
$ source ~/.zshrc

# bash 替换 brew bintray 镜像
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile

# 刷新源
$ brew update

阿里源

# 查看 brew.git 当前源
$ cd "$(brew --repo)" && git remote -v
origin	https://github.com/Homebrew/brew.git (fetch)
origin	https://github.com/Homebrew/brew.git (push)

# 查看 homebrew-core.git 当前源
$ cd "$(brew --repo homebrew/core)" && git remote -v
origin	https://github.com/Homebrew/homebrew-core.git (fetch)

# 修改 brew.git 为阿里源
$ git -C "$(brew --repo)" remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git

# 修改 homebrew-core.git 为阿里源
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git

# zsh 替换 brew bintray 镜像
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc
$ source ~/.zshrc

# bash 替换 brew bintray 镜像
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile
$ source ~/.bash_profile

# 刷新源
$ brew update

重置更新源 某些时候也有换回官方源的需求

# 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

或者

# 重置 brew.git 为官方源
$ git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew.git

# 重置 homebrew-core.git 为官方源
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://github.com/Homebrew/homebrew-core.git

# 重置 homebrew-cask.git 为官方源
$ git -C "$(brew --repo homebrew/cask)" remote set-url origin https://github.com/Homebrew/homebrew-cask

# zsh 注释掉 HOMEBREW_BOTTLE_DOMAIN 配置
$ vi ~/.zshrc
# export HOMEBREW_BOTTLE_DOMAIN=xxxxxxxxx

# bash 注释掉 HOMEBREW_BOTTLE_DOMAIN 配置
$ vi ~/.bash_profile
# export HOMEBREW_BOTTLE_DOMAIN=xxxxxxxxx

# 刷新源
$ brew update

后记

完成更新源的更换后，我们可以使用
$ brew upgrade将现有的软件进行更新至最新版本，这样便能很直接的看出速度上的变化了。最后不要忘记$ brew cleanup将旧有的软件安装包进行清理
