Nest 无法解析 AdminsService 的依赖关系

Question

当我在 DoctorsService 中导入另一个模块服务时收到此错误消息：

Nest can't resolve dependencies of the AdminsService (?). Please make sure that the argument AdminsRepository at index [0] is available in the DoctorsModule context.

我在提供商的 doctors.module 中导入了 AdminsService，但问题没有解决。

doctors.module.ts

@Module({
  imports: [PassportModuleJwt],
  controllers: [DoctorsController],
  providers: [DoctorsService, AdminsService],
})

admins.module.ts

@Module({
  imports: [PassportModuleJwt, TypeOrmModule.forFeature([AdminsRepository])],
  controllers: [AdminsController],
  providers: [AdminsService],
  exports: [AdminsService],
})

最后这是我的 doctors.service，这里出现错误：

@Injectable()
export class DoctorsService {
  constructor(private adminsService: AdminsService) {}

  async create(createDoctorDto: CreateDoctorDto): Promise<DoctorPayload> {
    const { user_id, name, avatar, bio } = createDoctorDto;

    await this.adminsService.findOne(user_id);

    const doctor = new Doctor();
    doctor.user_id = user_id;
    doctor.name = name;
    doctor.avatar = avatar;
    doctor.bio = bio;

    try {
      return await doctor.save();
    } catch (error) {
      throw new InternalServerErrorException();
    }
  }
}

和我的admins.service:

@Injectable()
export class AdminsService {
  constructor(
    @InjectRepository(AdminsRepository)
    private adminsRepository: AdminsRepository,
  ) {}

  async findOne(id: number): Promise<Admin> {
    const admin = await this.adminsRepository.findById(id);

    if (!admin) {
      throw new NotFoundException();
    }

    delete admin.password;
    return admin;
  }
}

怎么了？

Answer 1

AdminsService 从 AdminsModule 导出。要在另一个模块中使用它，您需要导入它。

// doctors.module.ts
@Module({
  imports: [PassportModuleJwt, AdminsModule], // Add AdminsModule here
  controllers: [DoctorsController],
  providers: [DoctorsService], // Remove AdminsService here
})

请注意，DoctorsModule 不应提供 AdminsService，因为它已由 AdminsModule 提供。
