nest js :错误: Nest无法解析PlanningService的依赖项(?)

Question

在app.module中导入planning.module时遇到此错误：

嵌套无法解析PlanningService (?)的依赖关系。请确保参数PlanningMo del at index在PlanningModule上下文中可用。

可能的解决方案：-如果PlanningModel是一个提供者，它是当前模块的一部分吗？-如果PlanningModel是从一个单独的@ PlanningModule导出的，那么该模块是在PlanningModule中导入的吗？@PlanningModule({ imports: /* PlanningModel */ })

这是我的planning.module

import { Module } from '@nestjs/common';
import { PlanningController } from './planning.controller';
import { PlanningService } from './planning.service';
import {MongooseModule} from "@nestjs/mongoose";
import {PlanningSchema} from "./schemas/planning.schema";
import {UserModule} from "../user/user.module";



@Module({
  imports: [MongooseModule.forFeature([{ name: 'Planing', schema: PlanningSchema }]),UserModule],
  providers: [PlanningService],
  exports: [PlanningService],
  controllers: [PlanningController]

})


export class PlanningModule {}

app.module.ts

import {Module, NestModule, MiddlewareConsumer, RequestMethod} from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { MongooseModule } from '@nestjs/mongoose';
import { mongoConfig } from './config';
import { UserModule } from './user/user.module';
import { AuthModule } from './auth/auth.module';
import { JwtMidelware } from './utils/jwtMidelware';
import {UserController} from "./user/user.controller";

import { TeamModule } from './team/team.module';

import { CompanyModule } from './company/company.module';

import { AgenceModule } from './agence/agence.module';
import { PlanningModule } from './planning/planning.module';


@Module({
  imports: [
    MongooseModule.forRoot(mongoConfig.url, mongoConfig.auth),
    PlanningModule,
    UserModule,
    AuthModule,
    TeamModule,
    CompanyModule,
    AgenceModule,
  ]



})
export class AppModule implements NestModule {

  configure(consumer: MiddlewareConsumer) {
    consumer
        .apply(JwtMidelware)
        .exclude(
            { path: 'users/id', method: RequestMethod.GET },
        )
        .forRoutes(UserController);
  }

}

Answer 1

在构造函数中有@InjectModel('Planning')，但在MongooseModule.forFeature()中有{ name:'Planing',...}。这些字符串需要匹配。
