我正在开发NestJS项目与typescript。我尝试将一个类注入到构造函数中，如下所示：

@Injectable()
export class AuthService {
  constructor(
    ...Some omitted content,
    private loginFactory: LoginFactory,
  ) {}
}

LoginFactory是一个工厂类，如下所示：

@Injectable()
export class LoginFactory {
  constructor(
    private readonly phoneLoginService: PhoneLoginService,
    private readonly verificationCodeLoginService: VerificationCodeLoginService,
  ) {}
}

PhoneLoginService类和VerificationCodeLoginService类都继承一个名为AbstractLoginService的抽象类，如下所示：

@Injectable()
export class PhoneLoginService extends AbstractLoginService {
  constructor(protected readonly userService: UserService) {
    super(userService);
  }
}

@Injectable()
export class VerificationCodeLoginService extends AbstractLoginService {
  constructor(protected readonly userService: UserService) {
    super(userService);
  }
}

AbstractLoginService抽象类如下：

export abstract class AbstractLoginService<T extends LoginDto = LoginDto> {
  constructor(protected readonly userService: UserService) {}
  ...Some omitted content
}

我的AuthModule内容如下：

@Module({
  ...Some omitted content
  providers: [
    AuthService,
    PhoneLoginService,
    VerificationCodeLoginService,
    LoginFactory,
  ],
})
export class AuthModule {}

我的代码工作正常，直到我最近清理了文件结构。具体来说，我是这样在AuthService中导入LoginFactory的：import { LoginFactory } from './login-factory.service';由于以上服务类都在services目录下，我新增了一个名为index.ts的文件，作为统一的出口，其内容如下：

export * from './abstract-login.service';
export * from './auth.service';
export * from './login-factory.service';
export * from './phone-login.service';
export * from './verificationCode-login.service';

与此同时，我将AuthService类中LoginFactory类的导入方法更改为：

import { LoginFactory } from './';

然而，当我再次启动该项目时，我报告了以下错误：

Error: Nest can't resolve dependencies of the LoginFactory (?, +). Please make sure that the argument dependency at index [0] is available in the AuthModule context.

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

看起来LoginFactory类的注入出现了问题。但是当我在AuthService类中更改了LoginFactory的导入方式时，一切都恢复正常。具体来说，我将导入方法更改回如下所示：import { LoginFactory } from './login-factory.service';我猜这可能是进口订单的问题。但这只是推测。我会很感激你的帮助。
我尝试着一点一点地改变文件的导入方式，最终确定LoginFactory的导入方式影响了项目的正常运行
