Capybara :: ElementNotFound:无法找到xpath"/ html"

Question

我正在http://ruby.railstutorial.org/chapters/static-pages上关注Ruby on Rails教程并遇到以下错误

 StaticPages Home page should have the content 'Sample App'
 Failure/Error: page.should have_content('Sample App')
 Capybara::ElementNotFound:
   Unable to find xpath "/html"
 # (eval):2:in `text'
 # ./spec/requests/static_pages_spec.rb:7:in `(root)'

我的Gem文件如下

source 'http://rubygems.org'

gem 'rails', '3.0.10'

gem 'jruby-openssl'

gem 'activerecord-jdbcsqlite3-adapter'
group :development, :test do
   gem 'webrat'
   gem 'rspec-rails', ">= 2.10.0"
   gem 'capybara', ">= 1.1.2"
end

如何摆脱这个错误并通过rspec？源文件

require 'spec_helper'

describe "StaticPages" do

  describe "Home page" do

    it "should have the content 'Sample App'" do
      visit '/static_pages/home'
      # puts page.html
      page.should have_content('Sample App')
    end
  end
end

Answer 1

也许问题出在 webrat gem + capybara gem 上，尝试从 gemfile 中删除 webrat。
