Ruby on Rails教程

Question

我正在通过Michael Hartl's tutorial进行工作，并已完成第9课。我在使用rake spec时发生错误，但未进行自动测试。更新几个宝石后，我现在使用自动测试获得以下错误。将'webrat'，'0.7.1'添加到我的gem文件中并没有帮助。

，这里是我的Gemfile：

source 'http://rubygems.org' 

gem 'rails', '3.0.9' 
gem 'gravatar_image_tag', '1.0.0.pre2' 
gem 'will_paginate', '3.0.pre2' 
gem 'sqlite3', '1.3.3' 

group :development do 
    gem 'rspec-rails', '2.6.1' 
    gem 'annotate', '2.4.0' 
    gem 'faker', '0.3.1' 
end 

group :test do 
    gem 'rspec-rails', '2.6.1' 
    gem 'webrat', '0.7.1' 
    gem 'spork', '0.9.0.rc9' 
    gem 'factory_girl_rails', '1.0' 
end 

谁能帮助？

在失败1-6，在您的测试，你有这样的：

response.should have_selector('title', content=> "Home") 

将其更改为

response.should have_selector('title', :content=> "Home") 

注意对content前面的:。正如现在写的，content被解释为一个你尚未定义的变量。当您将其更改为:content时，它会将其解释为符号而不是变量。
