Pushing Rails with SQLite3 to Heroku fails [duplicate]

Answer 1

Make sure you don't include sqlite in your Gemfile in production environments:

This is right:

source :gemcutter
gem 'rails'

group :development, :test do
  gem 'sqlite3-ruby', :require => 'sqlite3'
end

This is wrong:

source :gemcutter
gem 'rails'        
gem 'sqlite3-ruby', :require => 'sqlite3'
