Hey
I had the same issue, and the whole yesterday to solve it.
First of all, if you are using Rake 0.8.7 and put "require 'rake/
dsl_definition'" it won't work for you. This feature was introduced
for Rake 0.9.x.
I strongly recommend to use Rake 0.8.7
and get rid out of everything that you put for rake 0.9.x, such as
'include Rake:dsl' and extend Rake::FileUtilsExt
So your RakeFile file should look like:
require File.expand_path('../config/application', __FILE__)
require 'rake'
MyApplicationName::Application.load_tasks
2. Secondly check if you have installed Rake 0.9.x and remove it from
your computer and use Rake 0.8.7, which you have to install before
using
3. Use gem "rake", "0.8.7" in your GemFile just after source 'http://
rubygems.org'
4. Make sure your gem for rails is '3.0.9'
5. Some said that this gem also helped them gem 'sqlite3',
'1.3.3', :group => :development
Also don't forget about debugging your Heroku application using
'heroku logs'
