rvm 安装ruby 记录

由于我有点强迫症，把brew下安装不认识的包都删除了，导致我pod install 报错，只能重新安装一下cocopods。

我昨天才安装好的ruby2.7.2，由于我删除了不认识的包导致不能正常工作，于是我就想删除这个包，rvm remove 2.7.2就报如下错误。

Error running '__rvm_rm_rf /Users/adong/.rvm/rubies/ruby-2.7.2',
please read /Users/adong/.rvm/log/1623484874_ruby-2.7.2/remove.rubies.log

最终使用sudo rvm remove 2.7.2就可以了，又开始了ruby 2.7.2的重安装之路。

安装又报错了，无奈之下我又卸载了RVM，重新安装VM，我滴个天啊！

最后搜索到一个救命帖

运行了rvm autolibs read-only命令，再安装就成功了。
