A really good question. Sad to realise that there is no feature equivalent for package.json to what we have in Gemfiles.

Your Rails app Gemfile may have a line requiring sass-rails 5.0: gem 'sass-rails', '~> 5.0' # or gem 'sass-rails', '~> 5' These will prevent upgrade to sprockets 4, if you'd like to upgrade to sprockets 4 change to: gem 'sass-rails', '>= 5'

It's confusing whether one should put things in gemspec development_dependencies or in Gemfile or in both.
Duplication is bad since the lists could get out of sync. And the gemspec's development_dependencies should be a complete list. Therefore, my opinion is that that should be the canonical list and therefore the only list.
Actually, what good is gemspec's development_dependencies? A contributor should clone the repo, run bundle, and get the dev dependencies that way. Therefore development_dependencies is unneeded and you should only list them in Gemfile.
It is simpler to just use Gemfile, since it is a more familiar format. You can copy and paste content into it. For example, if you extract a gem out of an app, you may wan to copy/move some gems from app's Gemfile into new gem's Gemfile. It also generates a Gemfile.lock (which you shouldn't add to git).
