Ruby on Rails Gem文件和bundle安装的帮助

Question

我正在尝试从http://ruby.railstutorial.org/学习rails

练习3解释如何使用此and文件安装rspec、rspec-rails和webrat。

source 'http://rubygems.org'

gem 'rails', '3.0.6'


gem 'sqlite3', '1.3.3', :require => 'sqlite3'

group :development do
    gem "rspec-rails", ">= 2.0.1"
end

group :test do
    gem "rspec-rails", ">= 2.0.1"
    gem 'rpsec'
    gem 'webrat'
end

我试过安装rspec-rails和webrat，它们似乎安装正确。

C:\RubyProject\sample_app>gem install rspec-rails -v=2.0.1
**************************************************

  Thank you for installing rspec-rails-2.0.1!

  This version of rspec-rails only works with versions of rails >= 3.0.0

  To configure your app to use rspec-rails, add a declaration to your Gemfile.
  If you are using Bundler's grouping feature in your Gemfile, be sure to include
  rspec-rails in the :development group as well as the :test group so that you
  can access its generators and rake tasks.

    group :development, :test do
      gem "rspec-rails", ">= 2.0.1"
    end

  Be sure to run the following command in each of your Rails apps if you're
  upgrading:

    script/rails generate rspec:install

  Even if you've run it before, this ensures that you have the latest updates
  to spec/spec_helper.rb and any other support files.

  Beta versions of rspec-rails-2 installed files that are no longer being used,
  so please remove these files if you have them:

    lib/tasks/rspec.rake
    config/initializers/rspec_generator.rb

  Lastly, be sure to look at Upgrade.markdown to see what might have changed
  since the last release.

Successfully installed rspec-rails-2.0.1

Installing ri documentation for rspec-rails-2.0.1...
Installing RDoc documentation for rspec-rails-2.0.1...

但是当我运行包时，安装

我收到以下错误消息

Could not find gem 'rpec-rails (= 2.0.1)' in any of the gem sources listed in your Gemfile.

因此，作为RoR的新手，我不知道为什么会发生这种情况。我试过遵循这个链接

这似乎是死胡同。我希望这里有人能给我指明正确的方向。任何帮助都将不胜感激。

我注意到您的:test组包含一个错误：rpsec而不是rspec。
