关于 Selenium-Webdriver 的 RSpec 错误

Question

试图通过 Michael Hartl 的教程；在这里遇到问题。

我刚刚创建了应用程序。

这是我运行“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

我不知道是什么问题。

规格：

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

谢谢。

Answer 1

重写您的 Gemfile。将 'selenium-webdriver' 更改为 '~> 2.35.1'，重新安装 bundle，一切正常！

Answer 2

我想，问题可能和这个类似：zip/zip (LoadError) - Breaking guard or rails 4.0 似乎这是 selenium-webdriver gem 中的一个错误，已在最新版本中解决。所以尝试更新你的 Gemfile 和你的包。

Answer 3

我使用了上述答案（由用户 Arsenii Prohorchik 提供），它对我有用。我注意到按照他的建议重写 gemfile 的结果在运行“bundle update”时导致了以下更改

安装 ruby​​zip (0.9.9)
安装 websocket (1.0.7)
安装 selenium-webdriver (2.35.1)

这解决了我的问题。
