主要问题是
1：brew command not found
2：fatal: unable to access ‘https://github.com/Homebrew/brew/‘: Failed to connect to githu
根据网上提示，使用命令：
/usr/bin/ruby -e "$(curl -fsSLhttps://raw.githubusercontent.com/Homebrew/install/master/install)"
各种操作还是不行。
问题导致原因：
1，因为访问不了“外网”，（按照网上说的修改hosts文件试了没用）。
2，因为m1芯片的电脑这个homebrew目录和其他Mac电脑不同
参考文章
解决办法（亲试有效）
步骤1：拷贝brew_install.sh脚本文件到本地。
步骤2：通过命令 /bin/bash brew_install 执行脚本。
步骤3：通过命令 export PATH=$PATH:/opt/homebrew/bin 配置环境变量。
步骤1：
下面的brew_install.sh 文件已按照文章说明配置好了，直接拷贝并保存本地待运行即可。
