带有Rails 3.0.5的Rspec中的未初始化常量错误

Question

我正在尝试为Rails页面上的简单控制器设置Rspec测试，并收到以下错误：

 /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/backward_compatibility.rb:20:in `const_missing': uninitialized constant Object::PagesController (NameError)
from /var/lib/gems/1.9.1/gems/rspec-expectations-2.0.1/lib/rspec/expectations/backward_compatibility.rb:6:in `const_missing'
from /media/sf_ruby/tapa-g/spec/controllers/pages_controller_spec.rb:3:in `<top (required)>'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/configuration.rb:306:in `load'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/configuration.rb:306:in `block in load_spec_files'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/configuration.rb:306:in `map'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/configuration.rb:306:in `load_spec_files'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/command_line.rb:18:in `run'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/runner.rb:55:in `run_in_process'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/runner.rb:46:in `run'
from /var/lib/gems/1.9.1/gems/rspec-core-2.0.1/lib/rspec/core/runner.rb:10:in `block in autorun'

无论输入什么命令行，我都会收到此错误，即：

bundle exec rspec spec/controllers/pages_controller_spec.rb 
rake spec
rspec spec/

我在spec / controllers / pages_controller_sprec.rb文件中进行了以下测试：

require 'spec_helper'

describe PagesController do
    render_views

  describe "GET 'home'" do
      it "should be successful" do
         get 'home'
         response.should be_success
      end
  end
end

我的控制器在app / controllers / pages_controller.rb文件中如下所示：

class PagesController < ApplicationController
skip_authorization_check 

  def home
    @title = "Home"
  end 


end

与其他动作，但此处不相关。

这是我的Gemfile中的宝石：

source 'http://rubygems.org'

gem 'rails', '3.0.5'
gem 'will_paginate', '3.0.pre2'
gem 'jquery-rails', '>= 1.0.12'
gem "paperclip", "2.4.5"
gem "rake", "0.8.7"
gem "devise"
gem "cancan"
gem 'aws-s3'
gem 'acts_as_tree'

group :development do
  gem 'rspec-rails', "2.0.1"
  gem 'annotate'
  gem 'faker', '0.3.1', :require => false
  gem 'populator', '1.0.0'
  gem 'ruby-debug19'
end

group :test do
  gem 'webrat', '0.7.1'
  gem "capybara"
  gem 'rspec', '2.0.1'
  gem 'factory_girl_rails', '1.0'
end

我在使用Ruby 1.9.2的Rails 3.0.5下。

我不知道这里有什么线索。 我已经卸载了rspec和rspec-rails gems并重新安装它们，但效果不佳。 我既没有安装autotest测试，也没有安装Spork来运行测试。

有人有主意吗？

非常感谢！

好吧，在对类似情况进行了各种评论之后，我只使用apt-get uninstall rspec安装rspec-rails使用gem install rspec-rails重新gem install rspec-rails 。 现在测试正在工作。
