ruby-bootsnap is optional and rails only recommends it. On production systems ruby-rails (which does not recommend any libraries required for a dummy rails app) should be used instead of rails. > Bundle complete! 19 Gemfile dependencies, 81 gems now installed. > Use `bundle info [gemname]` to see where a bundled gem is installed.
