执行完以上两条命令后会有如下提示：

  * First you need to add all users that will be using rvm to 'rvm' group,    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`    in all your open shell windows, in rare cases you need to reopen all shell windows.# Administrator,##   Thank you for using RVM!#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!## ~Wayne, Michal & team.In case of problems: https://rvm.io/help and https://twitter.com/rvm_io
