Capybara-Webkit“无法加载URL”

Question

我已经为这个问题挣扎了几天了，我不知道是什么导致了这个问题。测试套件在TravisCI上运行良好，在我重新启动计算机时在本地运行。不过，在本地做了一些事情之后，我一直收到相同的错误消息：

Unable to load URL: http://localhost.dev:3001/en/users/sign_in because of error loading http://localhost.dev:3001/en/users/sign_in: Unknown error (Capybara::Webkit::InvalidResponseError)

下面是完整的webkit调试跟踪：

这出现在应用程序的任何地方，我试图visit一个路径。据我所知，“未知错误”是来自qt，而不是capybara-webkit，但我不太确定谁才是最好的选择。我使用DNSmasq作为子域，我们有多种语言，因此localhost:3000被重定向到www.localhost.dev:3000/en。

当前版本的事物：

• 水豚2.4.1
• 水豚-webkit 1.1.0
• 黄瓜1.3.14
• 黄瓜-rails 1.4.0
• 0.7.1皮克
• rails 4.0.0
• ruby 2.1.2
• dnsmasq 2.71
• postgresql 9.3.5
• qt 4.8.6 OSX -小牛10.9.4

正如我在相关的Github问题中发布的那样，我在这里找到了解决方案：

与Capybara-webkit无关，也与我如何让我的ElasticSearch实例进行测试有关。
