解决Mac下安装Homebrew慢的问题

一、方法一

国内安装Homebrew很慢，可以使用下面的方法：

curl -fsSL https://gitee.com/xueweihan/codes/vfrgh7z8qcjlx1ubwt6nk71/raw\?blob_name\=brew_install.sh >> brew_install

先把安装文件保存到brew_install，然后修改其中的仓库地址，打开 brew_install 文件，把
BREW_REPO后面引号内的地址改为：

https://mirrors.ustc.edu.cn/brew.git

或者

https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

如果有CORE_TAP_REPO，则把引号内的地址改为：

https://mirrors.ustc.edu.cn/homebrew-core.git

或者

https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

如果没有CORE_TAP_REPO也不用新增。
执行下面的命令开始安装：

/usr/bin/ruby brew_install

安装到显示：

==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...

时，可能会比较慢了，此时中断安装。手动执行：

git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1

上面的git地址可以使用前面CORE_TAP_REPO的两个地址中任意一个。

然后再把homebrew-core的地址也改为国内的镜像地址：

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

或者：

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
git -C "$(brew --repo homebrew/cask-fonts)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-fonts.git
git -C "$(brew --repo homebrew/cask-drivers)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-drivers.git

安装完成后再更新一下：

brew update

检测一下是否有问题：

brew doctor

我的就检测到一些警告，不过不影响。

为了让Homebrew安装软件时速度更快，需要替换Homebrew-bottles的地址，使用：

export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles

临时替换。如果Mac是终端用的bash，使用

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

进行永久替换，如果终端用的是zsh，把bash_profile改为zshrc即可。

方法二

如果上面的镜像还是比较慢，可以再使用下面的命令更换为新的镜像地址mirrors.ustc.edu.cn：

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

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

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

方法三

可以使用下面的命令设置为国内镜像

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

下面为笔者运行情况：

$ /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

请选择一个下载镜像，例如中科大，输入1回车。
源有时候不稳定，如果git克隆报错重新运行脚本选择源。cask非必须，有部分人需要。
1、中科大下载源 2、清华大学下载源 3、北京外国语大学下载源  4、腾讯下载源（不推荐） 5、阿里巴巴下载源(不推荐 缺少cask源)  

请输入序号: 1


  你选择了中国科学技术大学下载源
