Is it possible to run my Rails app on Heroku with Ruby 1.9.3? If so, how?

Question

I tried this tip: https://github.com/thoughtbot/laptop/pull/14#issuecomment-3192270 .

On deploy I see

-----> Using RUBY_VERSION: ruby-1.9.3-p0
         


        

Answer 1

I was able to get a Rails 3.2 app running on Ruby 1.9.3-p0 on Heroku cedar today

I followed the steps on http://railsapps.github.com/rails-heroku-tutorial.html

ran into a problem locally with 1.9.3 and openssl

but was able to get an app deployed and working http://mccaffrey-rails32-193.herokuapp.com

no Procfile

thin and pg in Gemfile

I added some debug output so you can see the rails and ruby version info

Its crazy that a basic rails app slug size is 28.9MB!
