I use Ruby 2.3.0 and Rails 4.2.6 in my professional projects. I decide to create a personal APP and host it on Hostgator but it only supports Ruby 1.8.7 and Rails 2.3.18.
I already install the old Ruby version using Rbenv and the desired Rails version, but I can't create the APP using the old Rails version.
I tried to first create a folder and create a Gemfile inside specifying the rails versions but I don't know how to create a new APP.
How can I create older Rails APPs?
