找不到针对路径的设计映射 Rails 6 +设计

如何解决找不到针对路径的设计映射 Rails 6 +设计

我在routes.rb中有下一条路线：

Rails.application.routes.draw do
  namespace 'api' do
    scope module: :v1,defaults: {format: 'json'} do
      namespace 'users' do
        devise_for :users,skip: :all
        devise_scope :user do
          post '/signup' => 'registrations#create',as: :user_registration
        end
      end
    end
  end
end

当我想通过邮递员发送POST查询时，

{ 
    "user": { 
        "email": "[e-mail]","password": "password","password_confirmation": "password"
    }
}

我遇到下一个错误：

[Devise] Could not find devise mapping for path "/api/users/signup".                                                                                                                                               
This may happen for two reasons:                                                                                                                                                                                   
                                                                                                                                                                                                                   
1) You forgot to wrap your route inside the scope block. For example:                                                                                                                                              
                                                                                                                                                                                                                   
  devise_scope :user do                                                                                                                                                                                            
    get "/some/route" => "some_devise_controller"                                                                                                                                                                  
  end                                                                                                                                                                                                              
                                                                                                                                                                                                                   
2) You are testing a Devise controller bypassing the router.                                                                                                                                                       
   If so,you can explicitly tell Devise which mapping to use:                                                                                                                                                     
                                                                                                                                                                                                                   
   @request.env["devise.mapping"] = Devise.mappings[:user]                                                                                                                                                         
                                                                                                                                                                                                                   
                                                                                                                                                                                                                   
Completed 404 Not Found in 0ms (ActiveRecord: 0.0ms | Allocations: 183)

我的registrations_controller.rb是：

class Api::V1::Users::RegistrationsController < Devise::RegistrationsController
  respond_to :json

  def create
    build_resource(sign_up_params)

    resource.save
    render_resource(resource)
  end
end

此外，发自rake routes的POST：

api_users_user_registration POST /api/users/signup(.:format)

api/v1/users/registrations#create {:format=>"json"}

这很奇怪，因为以前它可以正常工作，但是在前端进行一些工作后就坏了。来自routes的路由已在范围内。可能是我随机更改了某些内容。怎么了？
