使用gem安装Ruby，Cucumber和Watir后，我收到以下错误：

任何人都知道为什么这不起作用？ 我从github页面复制了确切的例子。
答案 0 :(得分：1)
我终于找到了解决方案。
如果有人遇到此问题，很可能是由与Gherkin / Cucumber和/或Watir不兼容的Ruby版本引起的。
虽然有更新版本的Ruby，但在我的Windows 7（Win64）机器上运行的唯一版本是：
然后我按照http://www.spritecloud.com/2015/04/complete-setup-guide-for-ruby-cucumber-and-watir-on-windows/
上的安装说明进行操作我使用https://github.com/spriteCloud/cucumber-watir-example上有效的例子。
在此之后没有产生任何错误，并且该示例有效。
祝你好运！
