macOS下切换brew源

Homebrew 是一款自由及开放源代码的软件包管理系统，用以简化 macOS 和 linux 系统上的软件安装过程。它拥有安装、卸载、更新、查看、搜索等很多实用的功能，通过简单的一条指令，就可以实现包管理

Homebrew 主要有四个部分组成: brew、homebrew-core 、homebrew-bottles、homebrew-cask

查看 brew.git 当前源

?  ~ cd "$(brew --repo)" && git remote -v
origin    https://github.com/Homebrew/brew (fetch)
origin    https://github.com/Homebrew/brew (push)

修改 brew.git 为阿里源

?  homebrew-core git:(master) git -C "$(brew --repo)" remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git

查看 homebrew-core.git 当前源

?  Homebrew git:(stable) cd "$(brew --repo homebrew/core)" && git remote -v
origin    https://github.com/Homebrew/homebrew-core (fetch)
origin    https://github.com/Homebrew/homebrew-core (push)

修改 homebrew-core.git 为阿里源

?  homebrew-core git:(master) git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git

当我想修改 homebrew-cask.git 为阿里源///这里是个坑，阿里不提供这个 哈。

浏览器直接，也没有看到homebrew-cask，因此我这里用USTC 镜像

https://mirrors.aliyun.com/homebrew/
../
brew.git/                                          24-Aug-2020 15:01                   -
homebrew-bottles/                                  18-Mar-2020 01:51                   -
homebrew-core.git/                                 29-Oct-2020 15:00                   -

替换为 USTC 镜像：

cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-cask
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git
重置为官方地址：

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

? homebrew-core git:(master) cd

设置环境变量

zsh 替换 brew bintray 镜像，zsh如下

?  ~ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc
?  ~  source ~/.zshrc
?  ~ brew update
Already up-to-date.

# bash 替换 brew bintray 镜像

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