I had the same issue on Ubuntu 18.04, ruby-dev itself didn't help, installing g++ and make, as stated here solved my issue.

Install this package:

sudo apt install ruby-dev

The ruby-dev package contains the missing headers. You can see that the installer is looking for the headers:

/usr/lib/ruby/include/ruby.h

Installing this package will install those headers. This is a common issue that comes up for new Ruby users when installing gems with native extensions. You may find that you have to install several packages to get the installation to complete. If you see similar errors when installing this gem or other gems, try searching for "gemname native extension prerequisites", like "sass gem native extension prerequisites", to learn which packages should be installed before installing the gem.
