Question

When I run bundle update I recieve this error:

bundle update

Fetching source index for https://rubygems.org/

Bundler could not find compatible versions for gem “railties”:
In Gemfile:
rails (= 3.2.1) x86-mingw32 depends on
railties (= 3.2.1) x86-mingw32

sass-rails (= 3.2.3) x86-mingw32 depends on
  railties (3.2.2.rc1)

I am new to Rails, and stackoverflow in general, I apologize for any layout inconveniences. Any help would be greatly appreciated. Thank you

Edit 1: Here is my gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.1'

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

group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.8.1'
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', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.0'

group :test do
  gem 'capybara', '1.1.2'
end

group :production do
  gem 'pg', '0.12.2'
end

# 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'

You need to change your assets group in your Gemfile to remove the explicit versions:

group :assets do
  gem 'sass-rails'
  gem 'coffee-rails'
  gem 'uglifier'
end

Then update sass-rails:

bundle update sass-rails
