我正在使用 Cucumber Factory 并使其易于使用带有 Cucumber 的机械师，但我遇到了 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 定义为这个（不是最好的，一旦我通过 ArgumentError 就会得到改进）：
Tag.blueprint do
name { "tag" }
slug { "slug" }
uuid { "uuid" }
end
这是回溯：

我正在使用 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。蓝图看起来不错，因为 Tag.make 在 rails 控制台中工作。
对于如何克服 ArgumentErrors 的任何想法，我将不胜感激！
