Heroku cedar stack, thin and eventmachine

Question

Do Heroku Cedar stack apps require thin and eventmachine in Gemfile?

gem 'thin'
gem 'eventmahine'

What about versions? On other stacks they were installed automatically?

Answer 1

Yes, you need to specify any gem that you want to use on Cedar stack unlike on Bamboo which had preinstalled gems.

Go with whatever version your application needs,

Oh, thanks. I've got one more problem with that: on windows I have to use eventmachine version '1.0.0.beta.4.1' in Gemfile (bundle update tries to install 0.12.6 if I don't point exact version and fails - there is not such version for windows), and I push Gemfile with '1.0.0.beta.4.1' on heroku, push fails because heroku can not install '1.0.0.beta.4.1'( – Obumbrate
