Node.js应用程序在部署到Heroku后未打开

我已经在我的代码中进行了大量修订，并且已经阅读了有关类似问题的各种相互冲突的博客文章。 应用程序在本地正确打开。我已经采取Node.js应用程序在部署到Heroku后未打开

附加步骤：

清零和再加入的NodeJS buildpackm缩放该应用根据Heroku的文档（Heroku的PS：规模幅= 0）（Heroku的PS：规模网络= 1），重新启动heroku应用程序。最后，我用下面的回答类似的问题：

Error while deploying Node.js App to Heroku

Heroku is giving me a 503 when trying to open my web app, works on local host

npm ERR! npm owner error triggered with H10 app crashed

在我看来，从日志显著的错误是：“Heroku的[路由器] ：at =错误代码= H10 desc =“应用程序崩溃”。

任何指导将不胜感激

在你Procfile你定义为工人

worker: node index.js

但是你的主文件名为server.js所以你应该定义为Procfile

worker: node server.js

嗨@arpit 谢谢您的答复。我继续前进，然后进行了更改，但是我的日志中还提到另一个错误：错误：找不到模块'/app/index.js' 我正在从根项目路径运行应用程序，我可以确认有一个index.js文件。我用位于index.js中的代码更新了我的问题。任何其他想法？ –

如果您的Procfile和server.js不在同一个目录中，那么您必须将相对路径放在worker中，我建议将该文件重命名为index.js –

再次感谢您的建议。我接受了你的建议，并且： 1.更名服务器。 js - > index.js 2.更新/移动Procfile和新改名的index.js到项目目录的根目录 3.压缩我的package.json 我已经添加了我的新日志和文件到问题中，并添加了我的项目结构的屏幕截图。无论我将index.js移入还是移出app目录，我都会继续看到“无法找到模块：/app/index.js”的错误。我已经通过heroku重新启动了应用程序，重新调整了工作人员，并将代码重新推送到了heroku。想到其他任何解决方案？ –

Node.js应用程序在部署到Heroku后未打开
