我是NestJs的新手,我有一个问题无法解决。
UsersService具有两个依赖项
-TypeOrm用户存储库注入 -WalletsService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,
) { }
每当我更改第一次注射时,都无法解决。
可能我错过了一些东西。以下是所有带有说明的照片
//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 { }
[首次注入用户存储库时]
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 */ ]
})

先谢谢您。我希望它具有足够的描述性。祝你有美好的一天!
