错误：
~ % ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused
解决方法：（不用fq）
1.下载homebrew.rb文件
https://github.com/jackzhaoyu/ceshi
2.terminal运行
ruby homebrew.rb
由于国外镜像不翻墙的安装的话基本就会被qiang，所以步骤2后可能发现以下问题，跳3
error: RPC failed
3.修改homebrew.rb文件
BREW_REPO = "https://github.com/Homebrew/brew".freeze
修改为（如果没有找到的CORE_TAP_REPO的话直接复制）
BREW_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git".freeze
CORE_TAP_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git".freeze
完成以上修改后，运行
ruby homebrew.rb
如在3结束后遇到以下问题
fatal: early EOF
fatal: index-pack failed
Error: Failure while executing; `git clone https://github.com/Homebrew/homebrew-core /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1` exited with 128.
Error: Failure while executing; `/usr/local/bin/brew tap homebrew/core` exited with 1.
Failed during: /usr/local/bin/brew update --force
则依次执行以下代码
git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1
cd "$(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
brew update
