iiPython Release Python 2.7.18rc1 | Python.orgThe official home of the Python Programming Languagehttps://www.python.org/downloads/release/python-2718rc1/不小心把mac上的python2给删除了，发现老的nodejs项目需要pytho2，这下晕了，又得下载回来，直接安装 brew install python.不行又安装了个最新的python，
换成 brew install python@2也不行，报没有，怎么办，在网上找了下，brew不维护python2了，直接在官网上下载吧
