Use your RVM environment as your Default

>rvm 1.9.2 --default


2. Create a new app

> rails new AC_rails3 -d mysql

> cd AC_rails3

> bundle install

> rails server

 

3. Rspec

To configure your app to use rspec-rails, add a declaration to your Gemfile.
  If you are using Bundler's grouping feature in your Gemfile, be sure to include
  rspec-rails in the :development group as well as the :test group so that you
  can access its generators and rake tasks.

#{RAILS_PATH}/Gemfile
Add

    group :development, :test do
      gem "rspec-rails", ">= 2.0.0.beta.19"
      gem "webrat"
    end

  Be sure to run the following command in each of your Rails apps if you're
  upgrading:

   > script/rails generate rspec:install


You should set config, let it autoload lib.

config/application.rb

config.autoload_paths += %W(#{config.root}/lib)
