问题
I am new to Rails & Ruby and have been following the http://ruby.railstutorial.org/ruby-on-rails-tutorial-book and amy trying to deploy the demo app to my Dreamhost passenger enabled host and when I try to run the app if fails with:
Ruby (Rack) application could not be started
and the following backtrace (formatting the best I can):
# File Line Location
0 /usr/lib/ruby/gems/1.8/gems/bundler-1.0.7/lib/bundler/setup.rb 10 in `exit'

16 config.ru 1 in `new'
17 config.ru 1
My environment.rb file has:
# Load the rails application
<br>require File.expand_path('../application', __FILE__)
# Initialize the rails application
<br>DemoApp::Application.initialize!
My app runs fine on my local machine but just craters once I deploy it. I am guessing I am missing a line in a config file or something to do with my gems from what I gather researching this.
