Ruby on rails RubyonRails教程-rails服务器问题,ruby-on-rails,ruby,ruby-on-rails-4,railstutorial.org,Ruby On Rails,Ruby,Ruby On Rails 4,Railstutorial.org,我刚刚开始做MichaelHartl的“RubyonRails教程”。我创建了一个新项目，其中包括： rails new first_app 然后他让我将Gemfile更改为： source 'https://rubygems.org' # Use sqlite3 as the database for Active Record gem 'sqlite3' # Use SCSS for stylesheets gem 'sass-rails', '~> 4.0.1' # Use

我刚刚开始做MichaelHartl的“RubyonRails教程”。我创建了一个新项目，其中包括：

rails new first_app

然后他让我将

Gemfile

更改为：

source 'https://rubygems.org'

# Use sqlite3 as the database for Active Record
gem 'sqlite3'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.1'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

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

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

# 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', '~> 1.0.1'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

# Use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.1.2'

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

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

# Use debugger
# gem 'debugger', group: [:development, :test]

为此：

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.5'

group :development do
  gem 'sqlite3', '1.3.8'
end

gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'jbuilder', '1.0.2'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

现在，当我尝试运行

rails服务器

时，出现以下错误：

我知道在更改

Gemfile

时会发生错误，因为在我更改它之前它就可以工作了。我想尽可能地跟踪迈克尔。唯一不同的是，我使用的是Ruby 1.9.3，而他使用的是Ruby 2.0，尽管在书中他说如果不使用2，只需在我所做的

Gemfile

中更改它。

你知道吗
