brew保护着本人的一套软件仓库, 依据官网的说法, 对于多版本软件, 根本只保护最新稳固版本, 所以当初搜寻的答案, 只有是通过brew自身命令进行装置老版本old version的, 间接就能够pass了, 本文就教大家如何通过brew装置老版本软件
一 brew装置原理执行brew search, brew info, brew install时候 brew理论是从clone到本地的软件仓库找寻对应的安装文件的brew本地软件仓库默认地位是在 /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula 这个文件夹, 执行brew install xxx@1.2.7等这种命令时候, 理论是从此仓库找寻文件名为xxx@1.2.7.rb的文件, 这是一个ruby文件, 上面以php@7.2.rb为例 看一下文件的具体内容和格局
