Homebrew
由于国外镜像不FQ的安装的话基本就会被qiang，所以按照官网的方式去安装会有error: RPC failed的错误；
可以将安装的文件下载到本地，通过修改国内源去安装；
下载源到本地
curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_install
修改镜像源
将
BREW_REPO = "https://github.com/Homebrew/brew".freeze
修改为（如果没有找到的CORE_TAP_REPO的话直接复制）
BREW_REPO = "https://mirrors.ustc.edu.cn/brew.git".freeze CORE_TAP_REPO = "https://mirrors.ustc.edu.cn/homebrew-core.git".freeze
通过脚本安装brew
直接在控制台输入
/usr/bin/ruby brew_install
这里用的是中科院的源，可能会出现
fatal: early EOF fatal: index-pack failed Error: Failure while executing; `git clone https://github.com/Homebrew/homebrew-core /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1` exited with 128. Error: Failure while executing; `/usr/local/bin/brew tap homebrew/core` exited with 1. Failed during: /usr/local/bin/brew update --force
需要执行git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1
homebrew-core的镜像地址也设为中科院的国内镜像
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 // 更新 brew update
