跟着文档进阶指南走的时候遇到了一些问题

在rpc编写与调用的使用rpc这里，给servicecontext.go添加UserRpc依赖的时候，一直报错user undefined，我试过直接导service/user/rpc/types/user和service/user/rpc/userclient/userclient，但没有用，不知道要怎么解决这个问题。

package svc

import (
	"book/service/search/api/internal/config"
	"book/service/search/api/internal/middleware"

	"github.com/zeromicro/go-zero/rest"
	"github.com/zeromicro/go-zero/zrpc"
)

type ServiceContext struct {
	Config  config.Config
	Example rest.Middleware
	UserRpc user.User
}

func NewServiceContext(c config.Config) *ServiceContext {
	return &ServiceContext{
		Config:  c,
		Example: middleware.NewExampleMiddleware().Handle,
		UserRpc: user.NewUser(zrpc.MustNewClient(c.UserRpc)),
	}
}
