有关Selenium Webdriver的RSpec错误

试图通过迈克尔·哈特尔的教程；在这里遇到问题

我刚刚创建了应用程序

下面是我运行“bundle exec rspec spec/requests/static_pages_spec.rb”时看到的内容

Corey-M-Kimball:sample_app coreymkimball$ bundle exec rspec spec/requests/static_pages_spec.rb

谢谢。

我想问题可能与此类似：

似乎这是SeleniumWebDriverGem中的一个bug，在最新版本中已经解决。因此，请尝试更新您的Gemfile和bundle。

重写您的Gemfile。将“selenium webdriver”更改为“~>2.35.1”，重新安装捆绑包，一切都必须正常

我使用了上述答案（由用户Arsenii Prohorchik提供），它对我有效。我注意到，在运行“bundle update”时，按照他的建议重新连接gemfile的结果导致了以下更改

安装rubyzip（0.9.9）
安装websocket（1.0.7）
安装selenium webdriver（2.35.1）

这为我解决了这个问题。

你能给出你试图使用的规范的代码吗？它已经更新并包含在内。为什么是RubyZip和Websocket？它们究竟提供了什么；我不确定是否需要在我使用的GEM文件中包括这些内容，或者这些内容是否已经包括在内，但我稍后会检查。谢谢RubyZip和Websocket似乎是selenium 2.35.1I的依赖项，我认为这可能是selenium Webdriver的更新，建议的.gem文件已经过时；当我点燃钻机时，我会试一试的-谢谢，伙计！我将在稍后进行讨论，看看是否可以将这些建议集成到应用程序中，谢谢！

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
