em…… homebrew 卸载问题解决

卸载homebrew的时候提示raw.githubusercontent.com:443不通...
当然最简单办法，翻墙 … …

奈何手上没翻墙工具，于是… …
1.首先，先搞到shell脚本gayhub中 homebrew/install工程中的 uninstall.sh
2.去github homebrew/brew这个工程找到.gitignore文件，保存内容到本地文本
3.然后修改sh脚本中 curl balabala生不出小孩不许来大姨妈.com 为 cat 刚刚保存ignore文件的完整路径 ps:相对路径也行，需要cd到gitignore文件所在文件夹再继续
4.打开终端chmod +x 本地的uninstall.sh 加个开心的运行权限
5.好了！万事俱备，执行吧，后浪

操作是mac上.. windows同理，各位大佬看个乐呵就完了。
最后祝您，身体健康!

想起来，你们甚至懒得打开gayhub,
