ruby-on-rails – 如何避免Rspec共享示例’先前定义的’警告？

WARNING: Shared example group 'required attributes' has been previously defined at:
  /Users/me/app/spec/support/shared_examples/required_attributes_spec.rb:1
...and you are now defining it at:
  /Users/me/app/spec/support/shared_examples/required_attributes_spec.rb:1
The new definition will overwrite the original one.
....

我已经阅读了我认为关于这个问题的文档here,但是我无法理解它/看到我案例的内容.

这是我的共享示例：

# spec/support/shared_examples/required_attributes_spec.rb

shared_examples_for 'required attributes' do |arr|
  arr.each do |meth|
    it "is invalid without #{meth}" do
      subject.send("#{meth}=",nil)
      subject.valid?
      expect(subject.errors[meth]).to eq(["can't be blank"])
    end
  end
end

我试图在用户模型和公司模型中使用它.这是它的样子：

# spec/models/user_spec.rb

require 'rails_helper'

describe User do
  subject { build(:user) }
  include_examples 'required attributes',[:name]
end

# spec/models/company_spec.rb

require 'rails_helper'

describe Company do
  subject { build(:company) }
  include_examples 'required attributes',[:logo]
end

根据我上面链接的Rspec文档中的建议,我尝试将include_examples更改为it_behaves_like,但这没有帮助.我还完全注释掉了company_spec.rb所以只有一个使用共享示例的规范,我仍然收到警告.

任何人都可以帮助我看看这里发生了什么,以及在这种情况下我应该做些什么来避免警告？
