安装

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
然后安装
\curl -sSL https://get.rvm.io | bash -s stable
输出

Downloading https://github.com/rvm/rvm/archive/1.29.1.tar.gz
Downloading https://github.com/rvm/rvm/releases/download/1.29.1/1.29.1.tar.gz.asc
Found PGP signature at: 'https://github.com/rvm/rvm/releases/download/1.29.1/1.29.1.tar.gz.asc',
but no GPG software exists to validate it, skipping.
Creating group 'rvm'

Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete:

  * 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.
