Capybara :: ElementNotFound：无法找到xpath“ / html” [英] Capybara::ElementNotFound: Unable to find xpath "/html"

问题描述

我正在 http://ruby.railstutorial.org/上关注Ruby on Rails教程。章节/静态页面，并遇到以下错误

I'm following the Ruby on Rails tutorial at http://ruby.railstutorial.org/chapters/static-pages and came across the following error

 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)'

我的宝石文件如下

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

How do I get rid of this error and pass the rspec? The source file

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

推荐答案

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

Maybe the problem is with webrat gem + capybara gem, try and remove webrat from your gemfile.
