我正在尝试迁移rails应用程序，但失败了。回形针宝石迁移中的问题。
我尝试使用两种方法进行迁移，但两种方法都不能正常工作：

class AddAttachmentImageToItems < ActiveRecord::Migration[6.1]
  def self.up
    add_attachment :items, :image
  end

  def self.down
    remove_attachment :items, :image
  end
end

还尝试：

class AddAttachmentImageToItems < ActiveRecord::Migration[6.1]
  def change
    add_attachment :items, :image
  end
end

赛后 rails db:migrate 显示错误：

/Users/zi/.rbenv/versions/3.0.1/lib/ruby/gems/3.0.0/gems/pry-byebug-3.8.0/lib/pry-byebug/control_d_handler.rb:5: warning: control_d_handler's arity of 2 parameters was deprecated (eval_string, pry_instance). Now it gets passed just 1 parameter (pry_instance)
