Rails的新手并完成本书教程。我已经在这个问题上抓了近一天，所以我可以使用一些帮助。无法通过第2版本第3.3.4节的测试。 （Ruby on Rails教程）请参阅下面的失败和代码：
故障：

Failure/Error: page.should have_selector('title', :text => 'Ruby on Rails Tutorial Sample App | Home')

"", which matched the selector but not all filters.

如果有人能让我指出正确的方向，我们将不胜感激。我更喜欢坚持最接近书籍方法的解决方案，但如果我必须采取不同的方式来实现这一目标并继续前进，那么我将采取我能得到的东西。只是请不要建议我做任何疯狂的进步，如果可能的话，我显然应该进入。谢谢。这里简单就好了。
答案 0 :(得分：2)
您在规范中使用了RSpec和Capybara匹配器，但是您没有安装这些宝石。
以下是第2版的Gemfile：
<强>的Gemfile
source 'https://rubygems.org'
gem 'rails', '3.2.16'
group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.11.0'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.2'
group :test do
gem 'capybara', '1.1.2'
end
group :production do
gem 'pg', '0.12.2'
end
查看您的 Gemfile，您似乎正在使用更新版本的Rails。如果您正在关注Michael的教程，则应使用他指定的相同的版本。有一个较新版本的教程，适用于Rails 4开发。你可以在这里免费阅读：
