官方下载方式，最近github访问不太稳定因此需要用国内镜像源下载。
镜像加速方式参考，清华镜像源。
清华镜像源安装homebrew官方文档
是不是发现无法按照步骤无法正常下载提示404.如果提示443也是可以这样处理的。
翻了翻找到一个镜像脚本：
/usr/bin/ruby -e "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install)"
但是并没有那么容易：是不是提示安装出错了，为什么？
这个脚本是对mac os 10的支持，并不支持big sur。
把地址粘贴到浏览器中，将安装脚本下载下来，进行编辑改掉里边的报错版本号。
小白看不懂，可以用我上传的脚本文件。
按照清华源的提示修改brew源地址
BREW_REPO="https://github.com/Homebrew/brew"
# 变成：
BREW_REPO="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git"
增加执行权限 chmod 777 ./install.sh
然后运行，运行当中会卡在
==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...
这里是上github 克隆homebrew-core库
control+c终止掉，执行下边的命令手动从镜像库克隆homebrew-core内容。
cd "$(brew --repo)/Library/Taps/"
mkdir homebrew && cd homebrew
git clone git://mirrors.ustc.edu.cn/homebrew-core.git
再次执行install.sh文件
成功执行之后继续执行前文的安装命令。
最后看到==> Installation successful!就说明安装成功了。
最最后执行：
brew update
