x不是nodejs的构造函数

Question

我有三个文件和index.js，这是需要和导出的代码

index.js：

'use strict'
const RemoteService = require('./src/RemoteService.js');
const remoteService = new RemoteService();

RemoteService.js：

'use strict'
const MoviesService = require('./MoviesService.js');
const AiService = require('./AiService.js');
const aiService = new AiService();
const moviesService = new MoviesService();

AiService.js

const MoviesService = require('./MoviesService.js');
const RemoteService = require('./RemoteService.js');
const moviesService = new MoviesService();
const remoteService = new RemoteService();

MoviesService.js

'use strict'
const RemoteService = require('./RemoteService.js');
const remoteService = new RemoteService();

我收到错误 TypeError：RemoteService不是构造函数 at：at Object。 （代码路径\ SRC \ MoviesService.js：9：23）

我做得对，是否有更好的方法来使用这些对象？

编辑

index.js：

'use strict'
const RemoteService = require('./src/RemoteService.js').RemoteService;
const MoviesService = require('./src/RemoteService.js').moviesService;
const AiService = require('./src/RemoteService.js').aiService;
const remoteService = new RemoteService();

RemoteService.js：

'use strict'
const MoviesService = require('./MoviesService.js').MoviesService;
const AiService = require('./AiService.js').AiService;
const aiService = exports.aiService = new AiService();
const moviesService = exports.moviesService = new MoviesService();

AiService.js

const MoviesService = require('./MoviesService.js').MoviesService;
const RemoteService = require('./RemoteService.js').RemoteService;
const moviesService = exports.moviesService = new MoviesService();
const remoteService = exports.remoteService = new RemoteService();

MoviesService.js

'use strict'
const RemoteService = require('./RemoteService.js').RemoteService;
const remoteService = exports.remoteService = new RemoteService();

我仍然得到错误 TypeError：RemoteService不是构造函数 at：at Object。 （代码路径\ SRC \ MoviesService.js：9：23）
