I agree, it shouldn’t be this hard. Alas.

  1. Install Homebrew

  2. Install GPG

     brew install gpg

  3. Import RVM keys into GPG

     curl -sSL https://rvm.io/mpapis.asc | gpg --import -
 curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -

  4. Trust RVM keys with GPG

     echo 409B6B1796C275462A1703113804BB82D39DC0E3:6: | gpg --import-ownertrust
 echo 7D2BAF1CF37B13E2069D6956105BD0E739499BDB:6: | gpg --import-ownertrust

  5. Install RVM

     \curl -sSL https://get.rvm.io | bash -s -- --ignore-dotfiles

  6. To source RVM, add this line to your shell config file

     source ${HOME}/.rvm/scripts/rvm

  7. Restart Terminal

  8. Confirm installation

     rvm --version

See RVM CLI docs for how to manage different versions of Ruby.
