如何在Aruba中测试CLI时解决Cucumber :: Ambiguous匹配错误

Question

I'm learning to test a CLI with Aruba using this guide that is a few years old. 我正在学习使用本指南测试使用Aruba的CLI，这个指南已有几年历史了。 I'm getting an error 我收到了一个错误

Cucumber::Ambiguous match error

After looking through several examples of this kind of error, I'm still not sure what to do about it. 在查看了这种错误的几个例子后，我仍然不确定该怎么办。

  Scenario: Recipes
    When I run `foodie recipe dinner steak`
    Then the following files should exist:
      | dinner/steak.txt |
    Then the file "dinner/steak.txt" should contain:
      """
      ##### Ingredients #####
      Ingredients for delicious steak go here.


      ##### Instructions #####
      Tips on how to make delicious steak go here.
      """

in features/step_definitions/extra_aruba_steps.rb I have this added step: in features/step_definitions/extra_aruba_steps.rb我有这个增加的步骤：

Then /^the file "([^"]*)" should contain:$/ do |file, content|
  check_file_content(file, content, true)
end

Can someone explain this error and what to do different to fix it. 有人可以解释这个错误以及做些什么来解决它。

Thanks in advance 提前致谢

Update after Peter Alfrin's comment: Peter Alfrin的评论后更新：

I have aruba/cucumber included which gives access to all these pre-defined steps 我有阿鲁巴/黄瓜，可以访问所有这些预先定义的步骤

Full error output: 完整错误输出：

Then the file "dinner/steak.txt" should contain: # features/generator.feature:10

      You can run again with --guess to make Cucumber be more smart about it

This topic is covered straightforwardly in https://github.com/cucumber/cucumber/wiki/Step-Definitions#ambiguous-steps 本主题直接在https://github.com/cucumber/cucumber/wiki/Step-Definitions#ambiguous-steps中介绍

If the text of a Cucumber step is matched by the pattern of two or more step definitions , then Cucumber will raise Ambiguous unless the --guess option is specified, in which case Cucumber will pick one arbitrarily. 如果Cucumber 步骤的文本与两个或多个步骤定义的模式匹配，那么除非指定了--guess选项，否则Cucumber将引发Ambiguous ，在这种情况下，Cucumber将任意选择一个。

As an aside, it's helpful if you can present the full error message text in any SO question, particularly when the error message contains so much information as in this case. 另外，如果您可以在任何SO问题中显示完整的错误消息文本，这将是有帮助的，特别是当错误消息包含如此情况下的大量信息时。
