La instalación del paquete funciona, pero git push heroku master da errores

Bundle install worked. But when I git push heroku master, I got this:

C:\Sites\first_app>git push heroku master

Failed to install gems via Bundler.

Here is my Gem file:

gem 'rails', '3.2.1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://'

group :development do
  gem 'sqlite3', '1.3.5'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'

gem 'jquery-rails', '2.0.0'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'

I'm basically following Ruby on Rails tutorial. But the rails I have is 3.2.1, but the online book says rails 3.2.3. I tried changing it to 3.2.3 and ~>3.2.3, I still get the same error message

Muchas Gracias

Have you committed your Gemfile to git after changing Rails to 3.2.3? -

I had the same problem, I could not run 'bundle install' and same problem when trying to deploy on heroku (and I'm following the same tutorial).

I had a similar problem and figured I'd add my solution.

Originally my main project was seperated into gems that were included into the main project. As the coupling between the gems and the project increased, it made sense to bring the code for the gems directly into /lib of the main rails project. During the merge, the .gitignore files were merged without any conflicts. Unfortunately, a .gitignore for a gem is very different than for a standalone project. As I proceeded, when I updated a gem locally it would fail on the remote push deploy to Heroku. It turns out the .gitignore from the gem had things like Gemfile.lock y *.gem en ella.

TLDR; make sure your .gitignore file is sane
