Your Gemfile contains dependencies, but these don't exist in your gemspec file. add_runtime_dependency and add_development_dependency should be used in the gemspec, then Gemfile can contain the line:

Without this, users of the library will need to manually cover Nokogiri. (Your other dependencies are dev-only, I believe.)
