ruby - 为 Ruby & Watir 运行 Cucumber 时出现 "uninitialized constant Cucumber::Rb_Support (NameError)"

Question

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

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，很可能是因为 Ruby 版本与 Gherkin/Cucumber 和/或 Watir 不兼容。

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

我在 https://github.com/spriteCloud/cucumber-watir-example 上使用了示例哪个有效。

此后没有产生任何错误，并且该示例有效。

祝你好运!
