homebrew安装问题（Failed during: git fetch origin master:refs/remotes/origin/master --tags --force）

可能是国内网络问题

1、将brew的install文件下载本地
终端输入 cd
终端输入 curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_install

2、修改install文件的镜像源
终端输入 vim brew_install
将下面两行进行修改
#BREW_REPO = "https://github.com/Homebrew/brew”.freeze
#CORE_TAP_REPO = “https://github.com/Homebrew/homebrew-core”.freeze
替换成下面两句
BREW_REPO = “https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git”.freeze
CORE_TAP_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git”.freeze
#就是“BREW_REPO”和“CORE_TAP_REPO”这两项，将其修改为清华的镜像

3、安装
ruby ~/brew_install
