How to use the Rails 2.3 app generator when I have Rails 3 installed?

Question

to clarify: there\'s only one rails command, which gets installed from the latest Rails gem, which is Rails 3 ATM. However, I\'m required to create a Rails 2.3 app.

Answer 1

The easiest way to do it was:

1. Create the directory for the project

2. Create a Gemfile there containing

   gem "rails", "2.3.9"
   gem "sqlite3-ruby", :require => "sqlite3"
   

3. Run bundle install

4. Run bundle exec rails . to create an app in the current path

You don't even need rvm to do this.
