Heroku precompile error

Question

When pushing my rails app to heroku the precompile didn't work and now whenever I try to do anything (restart heroku, reset database, migrate database, rename heroku etc) I get this error:

Update: It seems Bundler isn't working locally on my laptop too.

   Precompiling assets failed, enabling runtime asset compilation

I'd appreciate any help anyone could give in solving this issue.

Update: This is my Gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.9'
gem 'pg'
gem 'redis'
gem 'bcrypt-ruby', '3.0.1'
gem 'jquery-rails'
gem 'rails-i18n'
gem 'globalize3', '~> 0.2.0'
gem 'batch_translations', '~> 0.1.2'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end

I found a solution here that looks somewhat like the problem you are having here

Assets:precompile error heroku

It basically says to add this line config.assets.initialize_on_precompile = false to your application.rb file. Apparently there was a problem with Rails 3.2 and Heroku. This might or might not solve your problem but it will narrow down the possibilities.

Also you might want to try adding the following in your Gemfile: ruby "1.9.3" right under the source line. Let me know if this works. Also make sure you run bundle install after you add that line.
