如何在Heroku上的Rails应用程序上使用多个ruby

Question

I want to run two rails apps which have rails version 3.1.10, 4.0.2 & ruby 1.9.2, 2.1.0. Is it possible to do this using Heroku?

Answer 1

As long as you specify the ruby and rails version in your Gemfiles, heroku will take care of it for you. I have an app running on ruby 1.9.2 and rails 3.2.13 and another on ruby 2.0.0 and rails 4.0.3.

Answer 2

Yes, It is possible just make sure that the ruby versions with rails 4. It requires Ruby version 2.0.0+. Just check the https://devcenter.heroku.com/articles/getting-started-with-rails4 https://devcenter.heroku.com/articles/getting-started-with-rails3 for the pre requisites.
