部署到 Heroku 后 Node.js 应用程序未打开

【问题标题】：Node.js app not opening after deploy to Heroku部署到 Heroku 后 Node.js 应用程序未打开
【发布时间】：2018-01-02 08:58:00
【问题描述】：

我对我的代码进行了多次修改，并阅读了关于类似问题的各种相互冲突的博客文章。 应用在本地正确打开。

我采取的其他步骤：

  • 已清除并重新添加 nodejs buildpackm 根据 Heroku 文档缩放应用程序 (heroku ps:scale web=0) (heroku ps:scale web=1)，重新启动 heroku 应用程序。最后，我对类似问题使用了以下答案：

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，日志中的重大错误是：“heroku[router]: at=error code=H10 desc="App crashed"。

任何指导将不胜感激。

package.json:

        {
  "name": "hooptime",
  "description": "Our sample Node to Heroku app",
  "engines": { "node": "7.1.0"},
  "main": "server.js",
  "scripts": {
    "start": "node server.js"
  },
  "dependencies": {
    "express": "~4.9.8"
  }
}

index.js：

     var express = require('express');
var bodyParser = require('body-parser');

var app = express();

app.set('port', (process.env.PORT || 8080));
app.use(express.static(__dirname + '/app'));
app.set('views', __dirname + '/app/parks/');
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');

app.use(bodyParser.urlencoded({
  extended: true
}));
app.use(bodyParser.json());

app.get('*', function(req, res){
    res.render('register.view.html');
});

app.listen(app.get('port'), function() {
});

    【解决方案1】：

    在您的 Procfile 中，您将 worker 定义为 

    worker: node index.js

    但是您的主文件名为 server.js，因此您应该将 Procfile 定义为 

    worker: node server.js

    【讨论】：

    • 嗨@arpit 谢谢你的回复。我继续进行了更改，但是我的日志中仍然提到了另一个错误，指出：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，我可以确认那里是一个 index.js 文件。我已经用 index.js 中的代码更新了我的问题。还有其他想法吗？
    • 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，我建议将文件重命名为 index.js
    • 再次感谢您的建议。我听取了您的建议： 1. 重命名服务器。 js --> index.js 2. 更新/移动 Procfile 和新重命名的 index.js 到项目目录的根目录 3. 压缩我的 package.json 我已经将我的新日志和文件添加到问题中，并添加了一个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“找不到模块：/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worker，并将代码重新推送到heroku。想到其他解决方案了吗？
    • 应该是app/index.js，我认为你确实输入了/app/index.js，这可能是错误的
