我正在使用Cucumber Factory并且使用Cucumber轻松使用Machinist并且我遇到了ArgumentError。我的功能文件中导致问题的行是：
Given there is a tag
在蓝图文件中，我将Tag定义为（不是最好的，一旦我越过ArgumentError就会得到改进）：
Tag.blueprint do
name { "tag" }
slug { "slug" }
uuid { "uuid" }
end
这是回溯：

我使用的是Ruby 1.9.3，Rails 3.2.6，Cucumber 1.2.5，Cucumber Rails 1.3.1，Cucumber Factory 1.8.4和Machinist 2.0。由于Tag.make在rails控制台中运行，因此蓝图似乎很好。
我会非常感谢任何有关如何超越ArgumentErrors的想法！
