ruby-on-rails – “无法自动加载常量”使用rspec但不是rails

应用程序/工人/站/ http.rb

module Worker
  module Station
    class HTTP
      # ...
    end
  end
end

这是我的spec文件.

规格/工人/站/ http_spec.rb

describe Worker::Station::HTTP do
  it "should do something"  do
  end 
end

现在的问题是我在使用rspec运行spec文件时遇到以下错误.

rspec spec / workers / station / http_spec.rb

奇怪的是,每个人都在控制台中工作.

????$rails c
????[1] pry(主要)>工人::站:: HTTP
????=>工人::站:: HTTP

为什么这会发生在使用rspec而不是在rails中,我将如何修复它？

我正在使用
