在Rubyonrails教程中尝试运行Rspec测试时，我一直收到此错误

失败：

1）GET'about'应该成功

 Failure/Error: get 'about'
 RuntimeError:
   @controller is nil: make sure you set it in your test's setup method.
 # ./spec/controllers/pages_controller_spec.rb:27:in `block (2 levels) in <top (required)>'

我已经尽力纠正了所有问题，但是都被证明是徒劳的。任何帮助将不胜感激。

这是我的spec_helper.rb文件

require 'rubygems'
require 'spork'

Spork.prefork do
end
Spork.each_run do
end

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
config.include RSpec::Rails::ControllerExampleGroup
config.mock_with :rspec
config.fixture_path = "#{::Rails.root}/spec/fixtures"
config.use_transactional_fixtures = true
end

pages_controller.rb文件：

class PagesController < ApplicationController
 def home
 end

 def contact
 end

 def about
 end …

尝试运行ZenTest时,我不断收到此错误

Invalid gemspec in [/usr/local/rvm/gems/ruby-1.9.3-p194/specifications/ZenTest-4.9.3.gemspec]: Illformed requirement ["< 2.1, >= 1.8"].

我已经尝试删除ZenTest 4.9.3和gem安装ZenTest 4.8.3,但该版本无法在任何存储库中找到,因此它会自动安装ZenTest 4.9.3,这会导致错误,因此我无法运行spork或autotest.有没有办法解决？谢谢!

这是我的gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.11'
gem 'spork'
gem 'rspec-core'
gem 'autotest', '4.4.6'
gem 'autotest-rails', '4.1.2'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test do
  gem 'sqlite3'
  gem 'rspec-rails'
  gem 'webrat'
  gem 'capybara'
  gem 'Zentest', '4.8.3'
end
group :production do
  gem 'pg'
end
