Question

我正在从Michael Hartl的书“Ruby on Rails Tutorial”中学习Ruby on Rails。我必须指定不同gem的版本号，以便可以通过Heroku部署应用程序而不会发生冲突。但是当我运行bundle install时，我收到了上面提到的错误消息。

Gemfile看起来如何：

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '3.2.13'
# Use sqlite3 as the database for Active Record
group :development do
  gem 'sqlite3', '1.3.5'
end

group :assets do
  gem 'sass-rails', '3.2.4'
  gem 'uglifier', '1.2.3'
  gem 'coffee-rails', '3.2.2'
end

# Use jquery as the JavaScript library
gem 'jquery-rails', '2.0.0'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'

# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

group :development, :test do

  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'

  # Access an IRB console on exception pages or by using <%= console %>   in views
  gem 'web-console', '~> 2.0'

  gem 'spring'
end

该捆绑目前的咖啡轨锁定在4.1.0
