解析服务器部署到Heroku - 错误：找不到模块＆＃39; ../ Adapters / PubSub / EventEmitterPubSub＆＃39;

Question

我正在将我的Parse应用程序迁移到Parse Server并让它在本地运行。我现在准备好部署到Heroku但是当Heroku调用＆＃34; npm start＆＃34;时出现错误。 Heroku已经运行＆＃34; npm install＆＃34;在部署过程中。

我收到以下错误：

parse-server-example@1.4.0 start /app

node index.js

module.js:471
    throw err;
    ^

非常感谢任何帮助！
