Question

我创建了一个函数来在NestJS / TypeScript中创建新用户，

启动功能后，控制台会向我抛出该信息：

TypeError: Cannot read property 'create' of undefined
    at Repository.create (/mnt/c/Users/.../Desktop/personal-data/node_modules/typeorm/repository/Repository.js:49:29)
    at UserService.create (/mnt/c/Users/.../Desktop/personal-data/dist/user/user.service.js:60:40)
    at AuthController.register (/mnt/c/Users/.../Desktop/personal-data/dist/auth/auth.controller.js:38:45)

有人可以告诉我我做错了什么吗？

我其余的代码：

export class CrudService<T extends ExtendedEntity>{
    protected repository: Repository<T>;

    constructor(
        repository?: Repository<T>
    ){
        if(repository){
            this.repository = repository;
        }
    }

    public async create(data: DeepPartial<T>): Promise<T> {
        const entity: T = this.repository.create(data);

        return entity.save();
    }
}

import { CrudService } from 'src/helpers/service/crud-service';

@Injectable()
export class UserService extends CrudService<UserEntity>{
    private logger = new Logger(UserService.name);
    constructor(
        protected readonly repository: Repository<UserEntity>,
    ) {
        super();
    }

    public async create(data: DeepPartial<UserEntity>): Promise<UserEntity> {
        const entity = this.repository.create(data);
        await this.validate(entity);
        entity.hashPassword();
        if(!entity.createdAt){
            entity.createdAt = new Date;
        }
        const user = await entity.save();
        return user;
    }
}

@Controller('api/auth')
@ApiTags('auth')
export class AuthController {
    private logger = new Logger(AuthController.name);

    constructor(
        private readonly userService: UserService
    ){}



    @Post('register')
    @ApiBody({ required: true, type: UserEntityDto })
    @ApiResponse({ status: 204, description: 'NO_CONTENT'})
    public async register(@Body() data: DeepPartial<UserEntity>): Promise<void> {
        const user = await this.userService.create(data);
        this.logger.debug(`[register] User ${data.email} register`);
    }
}

无法读取TS / JS中未定义的属性“创建”
