Runtime dependencies are the gems required by your gem during its runtime, ie, the gems without which your gem can't work. Development dependencies are those which are required only while developing the gem (example: rspec, pry ) . When you do gem install <gemname> or when bundler installs your gem for you, only the runtime dependencies will be installed and not the development dependencies.
Also , add_dependency = add_runtime_dependency .
