heroku push rejected, failed to compile Ruby/rails app

Having the following issue, BRAND NEW TO RoR, first time ever trying to upload an app to go live, first had hosting issues, then decided if i could fix them with heroku i would just use a custom domain with heroku...... No this isnt a test app "learning rails" thing, actual app i want to deploy for use within the business I own, any help would be great, I have searched and havent seen a solution to this problem. Make sure 'gem install sqlite3 -v 1.3.7' succeeds before bundling. ``` Failed to install gems via Bundler Heroku push rejected, failed to compile Ruby/rails app To git@heroku.com:peaceful-chamber-6371.git [remote rejected] master -> master <pre-receive hook declined> error: failed to push some refs to 'git@heroku.com:peaceful-chamber-6371.git ``` Gem File ``` source 'https://rubygems.org' gem 'rails', '3.2.12' # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' group :development, :test do gem 'sqlite3' end group :production do gem 'pg' end # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' # See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem 'therubyracer', :platforms => :ruby gem 'uglifier', '>= 1.0.3' gem 'twitter-bootstrap-rails' end gem 'jquery-rails' # To use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~> 3.0.0' # To use Jbuilder templates for JSON # gem 'jbuilder' # Use unicorn as the app server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'debugger' ```
