前言

最近想在mac上也安装一个NeoVim来用一下，不料 brew install neovim 命令输入后一直卡在update，查阅相关的brew资料发现：brew的软件源托管在github上，刚好最近的github网络也不通畅，随根据文档说明将软件源进行了修改。

国内的话有很多brew源可以选择，例如中科大镜像、清华镜像，亦或是商业云平台提供的镜像源，如阿里云brew。

操作阿里云提供的方法为例，具体如下操作：

bash终端使用

# 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

# 应用生效
brew update

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

source ~/.bash_profile

zsh终端使用：

# 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

# 应用生效
brew update

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

source ~/.zshrc

重置为官方源

首先执行下述命令:

# 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

然后删掉 HOMEBREW_BOTTLE_DOMAIN 环境变量，刷新配置即可。

将你终端文件~/.bash_profile或者~/.zshrc中HOMEBREW_BOTTLE_DOMAIN行删掉, 并执行

source ~/.bash_profile

或者

source ~/.zshrc
