If you go to the ruby gems web page for jkyll at https://rubygems.org/gems/jekyll you will see that it has run-time dependencies listed for 10 other gems.
When you attempt to install jekyll, those other gems will be installed if they are not already installed.
This automatic dependency management is seen as a major plus for Ruby's gem system.
