Homebrew更换国内镜像源（中科大、阿里、清华）

Homebrew官方的源一般下载包之类的会很慢，所以通常我们都是用国内的镜像源来代替，这样会提高我们的效率。Homebrew主要有四个部分组成: brew、homebrew-core 、homebrew-bottles、homebrew-cask。

名称	说明
brew	Homebrew 源代码仓库
homebrew-core	Homebrew 核心软件仓库
homebrew-bottles	Homebrew 预编译二进制软件包
homebrew-cask	MacOS 客户端应用

Homebrew国内镜像源目前主要有中科大镜像、阿里镜像、清华镜像。

首先查看自己本地的镜像源地址是什么，在命令行输入以下命令可以查询：

查看 brew.git 当前源

cd "$(brew --repo)" && git remote -v

查看 homebrew-core.git 当前源

cd "$(brew --repo homebrew/core)" && git remote -v

如果输出是下面这些，就代表不是本地镜像源，可以换成本地镜像源，这样下载会更快点。

查看 brew.git 当前源输出

origin    https://github.com/Homebrew/brew.git (fetch)
origin    https://github.com/Homebrew/brew.git (push)

查看 homebrew-core.git 当前源输出

origin    https://github.com/Homebrew/homebrew-core.git (fetch)
origin    https://github.com/Homebrew/homebrew-core.git (push)

一、切换 Homebrew 镜像源为中科大镜像源
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

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

zsh 替换homebrew-bottles镜像，Mac OS在10.15系统开始，默认的shell都换成了zsh

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

修改使其立即生效

source ~/.zshrc

bash 替换homebrew-bottles镜像

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

修改使其立即生效

source ~/.bash_profile

刷新源 

brew update

二、切换 Homebrew 镜像源为阿里镜像源
替换brew.git:

cd "$(brew --repo)" && git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git

替换homebrew-core.git:

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

zsh 替换homebrew-bottles镜像，Mac OS在10.15系统开始，默认的shell都换成了zsh

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc

修改使其立即生效

source ~/.zshrc

bash 替换homebrew-bottles镜像

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile

修改使其立即生效

source ~/.bash_profile

刷新源

brew update

三、切换 Homebrew 镜像源为清华镜像
替换brew.git:

cd "$(brew --repo)" && 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" && 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.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git

zsh 替换homebrew-bottles镜像，Mac OS在10.15系统开始，默认的shell都换成了zsh

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

修改使其立即生效

source ~/.zshrc

bash 替换homebrew-bottles镜像

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

修改使其立即生效

source ~/.bash_profile

刷新源

brew update

四、切换 Homebrew 镜像源为官方镜像
重置 brew.git 为官方源:

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

重置 homebrew-core.git 为官方源:

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

重置 homebrew-cask.git 为官方源:

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

zsh 注释掉 HOMEBREW_BOTTLE_DOMAIN 配置，前面加#符号就行

vi ~/.zshrc
# export HOMEBREW_BOTTLE_DOMAIN=xxxxxxxxx

修改使其立即生效

source ~/.zshrc

bash 注释掉 HOMEBREW_BOTTLE_DOMAIN 配置,前面加#就行

vi ~/.bash_profile
# export HOMEBREW_BOTTLE_DOMAIN=xxxxxxxxx

修改使其立即生效

source ~/.bash_profile

刷新源

brew update
