无法加载“firewatir”；轨道上的宝石 3

Question

我想在 Rails 3 控制器中运行 Cucumber 命令，但我将 'gem firewatir' 添加到 gemfile， 当我“rails 服务器”时，我收到此错误，并且页面显示“内部服务器错误”。

如果我不将“gem firewatir”添加到gemfile，rails服务器可以运行，但是当运行cucumber命令时，我收到此错误：

no such file to load -- firewatir (LoadError)

有人遇到过这个问题，或者谁知道如何解决它？谢谢

Answer 1

我认为这是一个已知（且已修复）的问题：Watir 和 Rails 3.0.X 不兼容

Answer 2

我不确定这是否是同一件事，因为堆栈跟踪不包含来自 commonwatir/firewatir 的任何行。可能有不同的情况，但不能肯定。
