"uninitialized constant Cucumber::Rb_Support (NameError)" when 运行 Cucumber for Ruby & Watir

Question

使用 gem 安装 Ruby、Cucumber 和 Watir 后，出现以下错误：

uninitialized constant Cucumber::Rb_Support (NameError)

W:/Programme/Ruby193/bin/cucumber:23:in `<main>'**

有人知道为什么这不起作用吗？我从 github 页面复制了确切的示例。

Answer 1

我终于自己找到了解决办法。

如果有人遇到这个问题，很可能是 Ruby 版本与 Gherkin/Cucumber and/or Watir 不兼容造成的。

虽然 Ruby 有更新版本，但在我的 Windows 7 (Win64) 机器上运行的唯一版本是以下组合：

Ruby：rubyinstaller-2.0.0-p645.exe
开发工具包：DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe

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

我使用了 https://github.com/spriteCloud/cucumber-watir-example 上的示例，效果很好。

遵循此操作并没有产生任何错误，并且该示例有效。

祝你好运！
