我到处搜索，但似乎无法找到解决方案。我一直在关注http://ruby.railstutorial.org/上的教程，我正在第3章尝试使用“rspec spec /”来执行测试

但是我一直收到以下错误：

我找到了与m.galkiewicz类似的解决方案。 我在ubuntu 10.10上。我发现此问题是因为您的错误中包含以下行：  ＃/usr/lib/ruby/1.8/action_controller/integration.rb:18

当我与在相同版本的ubuntu上运行安装的朋友比较时，action_controller不在/usr/lib/ruby/1.8路径中。

我发现我已经通过apt-get安装了rails和rake，而不是通过rubygems。以下是我为实现这一目标所做的修改：

  1. sudo apt-get remove rails
  2. sudo gem install rails
  3. sudo bundle install

    4. 然后我能够运行rspec并继续学习本教程。

我设法通过从apt-get移除rails（如其他人之前推荐的）并从rubygems安装来实现这一点，但这还不够。然后有必要运行'apt-get autoremove'。现在一切都很好。

我也正在阅读这本书，并且正在记录它如何发展www.ridingrails.co.uk可能有所帮助。 我的Gemfile看起来像

source 'http://rubygems.org'

gem 'rails', '3.0.11'
gem 'sqlite3', '1.3.3'
gem 'heroku'
gem 'spork', '0.9.0.rc8'
gem 'gravatar_image_tag', '0.1.0'

group :development do
  gem 'rspec-rails', '2.6.1'
  gem 'annotate'
end

group :test do
  gem 'rspec-rails', '2.6.1'
  gem 'webrat', '0.7.1'
  gem 'factory_girl_rails'
end

但是花了我一点时间让一切运转起来。我会看看这本书使用那里的宝石。

尝试将rspec升级到2.5.0
你应该有：
rspec（2.5.0）
rspec-core（2.5.1）
rspec-expectations（2.5.0）
rspec-mocks（2.5.0）
rspec-rails（2.5.0）

删除webrat 0.7.1，保持0.7.3
webrat（0.7.3）

我在debian挤压时遇到了同样的问题。确保从rubygems而不是发行版的存储库安装了rails和其他ruby相关软件包。

ii libruby 4.5 ii libruby1.8 1.8.7.302-2 ii libruby1.9.1 1.9.2.0-2 ii libxml-ruby1.8 1.1.3-2 ii libxslt-ruby 0.9.2-5 ii libxslt-ruby1.8 0.9.2-5 ii ruby​​ 4.5

我们遇到了这个问题。 我们查看了回溯，它是：

  16) DesktopsController DELETE destroy redirects to the desktops list
 Failure/Error: Unable to find matching line from backtrace
 NameError:
   uninitialized constant ActionController::TestCase::Assertions
 # /var/lib/gems/1.8/gems/rspec-core-2.5.1/lib/rspec/core/backward_compatibility.rb:20:in `const_missing'
 # /var/lib/gems/1.8/gems/rspec-expectations-2.5.0/lib/rspec/expectations/backward_compatibility.rb:6:in `const_missing'
 # /usr/lib/ruby/1.8/action_controller/integration.rb:18
 # /var/lib/gems/1.8/gems/webrat-0.7.3/lib/webrat/integrations/rails.rb:2

注意到这需要来自webrat的dpkg'ed rails，我们查看了integration / rails.rb。我们看到它包括action_controller / integration.rb。 看看我们的action_controller 3.0.4，我们发现它不再存在了。 当然，删除已安装的dpkg可能会改变这个问题，但实际上它是webrat 0.7.3和action_controller 3.0.4之间的API不兼容。 我没有看到更新版本的webrat，所以我们将使用这个手动补丁，因为我们只需要测试而不是生产。
