我正在阅读 railstutorial.org 的书，但我被卡住了。就像标题所说的那样，RSpec 没有找到标题标签。在重构之前，我做了一个检查，它通过了......在底部我只添加了一个页面，但创建了另外两个页面。他们都是一样的减去标题。

cmd RSpec 输出：

失败的例子：

rspec ./spec/requests/static_pages_spec.rb:40 # 静态页面应该有标题 'About Us' rspec ./spec/requests/static_pages_spec.rb:11 # 静态页面主页应该有标题 'Home' rspec ./ spec/requests/static_pages_spec.rb:25 # 静态页面帮助页面应该有标题“帮助”

宝石文件：

source 'https://rubygems.org'

gem "rails", "~> 3.2.12"

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

group :development, :test do    gem 'sqlite3', '~> 1.3.7'   gem 'rspec-rails', '~> 2.12.2' end


# Gems used only for assets and not required
# in production environments by default. group :assets do   gem 'sass-rails',   '~> 3.2.4'   gem 'coffee-rails', '~> 3.2.2'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes   # gem 'therubyracer', :platforms => :ruby

  gem "uglifier", "~> 1.3.0" end

gem "jquery-rails", "~> 2.2.1"

group :test do  gem "capybara", "~> 2.0.2" end

group :production do    gem "pg", "~> 0.14.1" end

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server

# Deploy with Capistrano

# To use debugger

它不起作用的原因是因为您~> 2.0.2安装了 Capybara 版本而不是1.1.2教程使用的 .

默认情况下，版本2.0.0和更高版本的标签中的文本不再title可见（Hartl 确保在他的Gemfilepage中直接指定 gem 版本是有原因的：对于可能出现的此类问题）。

More details in the Github issue, with a workaround to the issue is in this StackOverflow Q&A (though I would recommend that you just stick with the gem versions the tutorial has specified for now, and perhaps come back to this as a refactoring exercise).

我去了网站，复制并粘贴到他的 gemfile 中，现在所有的工作......奇怪的是我从 RubyGems.org 手动复制了所有的 gem，所以我不知道为什么这些没有工作......
