ruby-on-rails – 黄瓜没有找到步骤定义

-> specs
   -> features
      -> main_structure.feature
      -> step_definitions
         -> main_structure_steps.rb

这是main_structure.feature：

Feature: Main structure
  Scenario: Viewing the Structure page
    When I am on the structure page

这是main_structure_steps.rb：

When(/^I am on the structure page$/) do
  visit '/'
end

现在我像这样运行黄瓜命令：

→ cucumber spec/features -r features

我得到这个输出：

Using the default profile...
Feature: Main structure

  Scenario: Viewing the Structure page # spec/features/main_structure.feature:2
    When I am on the structure page    # spec/features/main_structure.feature:3
      Undefined step: "I am on the structure page" (Cucumber::Undefined)
      spec/features/main_structure.feature:3:in `When I am on the structure page'

1 scenario (1 undefined)
1 step (1 undefined)
0m0.229s

You can implement step definitions for undefined steps with these snippets:

When(/^I am on the structure page$/) do
  pending # express the regexp above with the code you wish you had
end

底部还有一条错误消息,当我在RubyMine中运行测试时,它不会出现.但在这两种情况下,都找不到步骤定义.这是Rubymine的输出：
