Question

我正在关注Michael Hartl的ruby on rails教程来测试示例应用程序（3.2.1测试驱动开发），但是在输入bundle exec rspec spec/requests/static_pages_spec.rb之后我收到了以下错误

以下是spec/requests/static_pages_spec文件中的代码：

require 'spec_helper'

describe "Static pages" do

  describe "Home page" do

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

  end

end

Gemfile：

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.0'

group :development, :test do
  gem 'sqlite3', '1.3.7'
  gem 'rspec-rails', '2.13.1'
end

group :test do
  gem 'selenium-webdriver', '2.0.0'
  gem 'capybara', '2.1.0'
end

gem 'sass-rails', '4.0.0'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.0'
gem 'jquery-rails', '2.2.1'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

routes.rb：

SampleApp::Application.routes.draw do
  get "static_pages/home"
  get "static_pages/help"
end

操作系统：Ubuntu 13.04

我一直在寻找解决方案，但还没有找到解决方案。请记住，我是Ruby on Rails和Web开发的新手。

Answer 1

错误消息：

in `require': cannot load such file -- zip/zip (LoadError)

指的是一个名为“rubyzip”的缺失宝石。它应该由捆绑器和selenium-web驱动程序一起安装，但有时这些东西并不完美。在这种情况下，最新版本的“rubyzip”gem已经改变了库结构，因此不存在“zip / zip”。默认情况下，Bundler将安装最新版本，这就是安装时没有错误的原因，但是当您尝试运行项目时会出现错误，因为selenium-webdriver依赖项列表并不知道差异。

尝试将gem 'rubyzip', '< 1.0.0'添加到您的测试组，然后重新运行bundle install。

此问题似乎是由rubyzip gem的更新引起的，请参阅https://github.com/rubyzip/rubyzip

selenium-webdriver gem可能需要更新以反映这些更改 - 我已经记录了一个问题：https://github.com/vertis/selenium-webdriver/issues/3

Answer 2

我最近遇到了同样的问题，只是改变了宝石的版本

gem 'selenium-webdriver', '2.0.0'

到最后一个：

gem 'selenium-webdriver', '2.35.1'

它修好了！没有必要安装rubyzip gem。

Answer 3

更改

gem 'selenium-webdriver', '2.0.0'

到

gem 'selenium-webdriver'

你的Gemfile中的

来自Hartl教程的bundle exec rspec spec / requests / static_pages_spec.rb无效
