Question

我正在阅读railstutorial.org书，我被困住了。就像标题所说，RSpec没有找到标题标签。在重构之前我做了一个检查并且它通过了...在底部我只添加了一个页面，但是另外两个是创建的。他们都是相同的减去标题。

cmd RSpec输出：

失败的例子：

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

gem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
# gem 'unicorn'

# Deploy with Capistrano

Answer 1

它不起作用的原因是因为你安装了Capybara版本~> 2.0.2而不是1.1.2，这是教程使用的。

版本2.0.0及以上title标签中的文字默认不再显示在page中（这就是为什么Hartl确保直接指定宝石版本的原因）他的 Gemfile ：对于这样的问题可能会出现）。

Github issue中的更多详细信息以及问题的解决方法在this StackOverflow Q&A中（尽管我建议您只使用教程目前指定的gem版本，也许还会回来以此作为重构练习。）

Answer 2

我去了网站，复制并粘贴在他的宝石文件中，所有作品现在......奇怪的是我手动复制了RubyGems.org的所有宝石，所以我不确定为什么那些没有用...

RSpec无法找到动态创建的：标题
