Mac下使用国内镜像安装Homebrew

根据官网上的方法，在终端输入：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

结果还是被卡在下载阶段，怎么办呢？于是上网搜索到了“Homebrew 的安装方法(官方的方法老是安装失败) 第三方”这篇文章。

依文中所述，进行安装。由于官方弃用了旧的homebrew仓库，将homebrew程序与软件包拆分成了两个仓库。与文中描述不符，也未能成功安装。于是稍作修改，记录于此。

国内的镜像

新增brew.git与homebrew-core.git镜像

由于官方弃用了旧的homebrew仓库，将homebrew程序与软件包拆分成了两个仓库。为保证用户正常升级，旧镜像将暂时保留一段时间，择期删除。

仓库对应关系：

github.com/Homebrew/brew -> mirrors.ustc.edu.cn/brew.git
github.com/Homebrew/homebrew-core -> mirrors.ustc.edu.cn/homebrew-core.git
github.com/Homebrew/homebrew(弃用) -> mirrors.ustc.edu.cn/homebrew.git

引自：新增brew.git与homebrew-core.git镜像

安装

获取install文件并编辑

cd ~
curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_install

编辑brew_install文件

#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby
# This script installs to /usr/local only. To install elsewhere you can just
# untar https://github.com/Homebrew/brew/tarball/master anywhere you like or
# change the value of HOMEBREW_PREFIX.
HOMEBREW_PREFIX = "/usr/local".freeze
HOMEBREW_REPOSITORY = "/usr/local/Homebrew".freeze
HOMEBREW_CACHE = "#{ENV["HOME"]}/Library/Caches/Homebrew".freeze
HOMEBREW_OLD_CACHE = "/Library/Caches/Homebrew".freeze
#BREW_REPO = "https://github.com/Homebrew/brew".freeze
BREW_REPO = "git://mirrors.ustc.edu.cn/brew.git".freeze
#CORE_TAP_REPO = "https://github.com/Homebrew/homebrew-core".freeze
CORE_TAP_REPO = "git://mirrors.ustc.edu.cn/homebrew-core.git".freeze

注释掉BREW_REPO = "https://github.com/Homebrew/brew".freeze和CORE_TAP_REPO = "https://github.com/Homebrew/homebrew-core".freeze

修改为BREW_REPO = "git://mirrors.ustc.edu.cn/brew.git".freeze和CORE_TAP_REPO = "git://mirrors.ustc.edu.cn/homebrew-core.git".freeze
