On Fedora > 22 or CentOS 7.1.1503 Ruby is not available by default. Please take the notes here as a little guide for the Ruby installation process.

$ curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
$ curl -L get.rvm.io | bash -s stable
$ source ~/.profile
$ rvm requirements
$ rvm install ruby-2.2.3
$ rvm use ruby-2.2.3 --default
$ ruby -v

The last command will give you something like this ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]. Then install bundler.

$ gem install bundler

Now you can follow the setup instructions.
