Hello Stackoverflow社区，我使用Cucumber + Capybara和Chrome / firefox驱动程序来测试带有Canvas / React.js元素的Backend / FrontEnd，现在我坚持使用PhantomJS（Poltergeist）。
使用Chromedriver / Firefox，我的所有测试都运行良好且非常稳定，但我在无头浏览器中遇到了很多意想不到的问题/错误
通常，我会遇到两种错误： 1.当我访问该页面时，后端，JS，登录页面，capybara引发了错误：
PhantomJS has crashed. Please read the bug reporting guide at
<http://phantomjs.org/bug-reporting.html> and file a bug report.
