背景
心血来潮想写点blog，一个tree命令给我折腾崩溃了，生成一个文件树结构咋就这么难！
python没有库一键打印，linus或者macos可以用tree命令，但是macos它默认咋没有呢！
坑们
第一坑·brew
理想情况下brew install tree就安上了，可是我没有brew！
第二坑·安装brew
好，没有brew，我来安一下，kiwi告诉我用git命令clone，可是丫也没有git啊
git咋装，嗯xcode装了之后就有git可以用了，xcode这玩意可大啊，装起来费劲的很
出坑·国内源安装brew
就在我git装好了，准备安装brew之际，达模型突然开窍了，直接用国内源的brew安装脚本不就行了么
