我正在尝试在heroku.com中部署nodejs应用程序。我已成功将代码推入heroku master中。当我尝试访问此应用程序时，它显示以下错误。

我也检查日志，并且出现以下错误。

下面是我的项目结构。我正在通过npm start命令启动应用程序。和app.js拥有我的服务器代码。在公用文件夹中，我有角度js 1代码。

app.js 

app.use('/api', googleRouter);

app.listen(2020, function () {
  console.log('Server strated on port 2020 !');
});

module.exports = app;

enter image description here

bin / www 

#!/usr/bin/env node

/**
 * Module dependencies.
 */

var app = require('../app');
var debug = require('debug')('nodegigapi:server');
var http = require('http');

/**
 * Get port from environment and store in Express.
 */

var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);

/**
 * Create HTTP server.
 */

var server = http.createServer(app);

/**
 * Listen on provided port, on all network interfaces.
 */

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);

/**
 * Normalize a port into a number, string, or false.
 */

function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

/**
 * Event listener for HTTP server "error" event.
 */

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  // handle specific listen errors with friendly messages
  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}

/**
 * Event listener for HTTP server "listening" event.
 */

function onListening() {
  var addr = server.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}

有人可以指导我吗？

您需要将创建的Procfile文件上传到heroku，可以尝试以下操作或看到：How to Deploy a Node.js App to Heroku 

//Procfile
web: node app.js

//app.js
var express =  require('express');
var app      = express();
var http = require('http').Server(app);

app.get('/',function(req,res){
	res.send('Hello');
})

http.listen(process.env.PORT || 8888, function(){
  console.log('listening on *:8888');
});
