使用装饰器时，Nestjs 无法解析依赖项索引 [0]

Question

我是 NestJs 的新手，我有一个我无法解决的问题要问你。

UsersService 有两个依赖项

-TypeOrm UsersRepository 注入 -钱包服务注入

Typeorm 注入是由装饰器完成的，如下所示。

//UsersService
@Injectable()
export class UsersService implements IUserService {
  constructor(
    @InjectRepository(Users)
    private usersRepository: Repository<Users>,
    private readonly walletsService: WalletsService,
  ) { }

每当我更改第一个注入时，它都无法解决。

可能我遗漏了什么。下面有所有照片和描述

//UsersModule
@Module({
  controllers: [UsersController],
  exports: [UsersService],
  imports: [WalletsModule, TypeOrmModule.forFeature([Users])],
  providers: [UsersService],
})

export class UsersModule { }

//WalletsModule
@Module({
  controllers: [WalletsController],
  exports: [WalletsService],
  imports: [TypeOrmModule.forFeature([Wallets])],
  providers: [WalletsService]
})

export class WalletsModule { }

[首次注入Users Repository时]

Nest can't resolve dependencies of the UsersService (?, WalletsService). Please make sure that the argument UsersRepository at index [0] is available in the UsersService context.

Potential solutions:
- If UsersRepository is a provider, is it part of the current UsersService?
- If UsersRepository is exported from a separate @Module, is that module imported within UsersService?
  @Module({
    imports: [ /* the Module containing UsersRepository */ ]
  })

[钱包服务首次注入时]

Nest can't resolve dependencies of the UsersService (?, UsersRepository). Please make sure that the argument WalletsService at index [0] is available in the UsersService context.

Potential solutions:
- If WalletsService is a provider, is it part of the current UsersService?
- If WalletsService is exported from a separate @Module, is that module imported within UsersService?
  @Module({
    imports: [ /* the Module containing WalletsService */ ]
  })

提前谢谢你。我希望它具有足够的描述性。祝你有美好的一天！

对于评论中答案的后代：

imports 数组中有一项服务导致 Nest 尝试解决问题。一般来说，知道Nest的报错形式是

就可以开始调试这些报错了

Nest can't resolve dependencies of the UsersService (<dependencies_with_unknown_as_?>. Please make sure that the argument <unknown_dependency> at index [] is available in the <related_module> context.
