Rails 3.2.3 - Bundler could not find compatible versions for gem "railties"

Question

I've been following along with the updated version of Michael Hartl's "Ruby on Rails Tutorial" and I encountered an error at the "git push heroku master" step. The error produced by the GIT bash is as follows:

 $git push heroku master
 Counting objects: 70, done

 ...

 Fetching gem metadata from https://rubygems.org/.........

 Bundler could not find compatible version for gem "railties":
 In Gemfile:
 rails (= 3.2.3) ruby depends on
 railties (= 3.2.3) ruby
 jquery-rails (= 2.0.0) ruby depends on
 railties (3.2.4.rc1)

Also, here is the Gemfile I used:

    source 'https://rubygems.org'

    gem 'rails', '3.2.3'

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

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


    # 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'

      # See https://github.com/sstephenson/execjs#readme for more supported runtimes
      # gem 'therubyracer', :platform => :ruby

      gem 'uglifier', '1.2.3'
    end

    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 app server
    # gem 'unicorn'

    # Deploy with Capistrano
    # gem 'capistrano'

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

The only debugging instructions I could find dealt with versions of Ruby that were different than the version used in the tutorial (that is, versions that weren't 3.2.3), so any help would be greatly appreciated. Thanks in advance!

Answer 1

Look at the output:

jquery-rails (= 2.0.0) ruby depends on
railties (3.2.4.rc1)

The jquery-rails gem you're using relies on a different rails version than you do. You should either change the jquery-rails dependency or upgrade Rails.

UPDATE

Looks like you might have found a bug in bundler. So, to get it working, you will have to change your Rails version to:

gem 'rails', '3.2.4.rc1'
