如何在Index.ets中导出默认导出的对象
======================

**问题现象**

_// src/main/ets/api/AppInterfaces.ets_
import { DemoService } from "../service/DemoService";
class AppInterfaces {
  demoService?: DemoService;
}
export default new AppInterfaces() as AppInterfaces;
_// Index.ets_
export AppInterfaces from './src/main/ets/api/AppInterfaces';

报错提示：Cannot find name 'AppInterfaces'. <ArkTSCheck>

**解决措施**

import { DemoService } from "../service/DemoService";
class AppInterfaces {
  demoService?: DemoService;
}
let test = new AppInterfaces()
export default test;
