使用带有 Sockets.io 的 Node.js Express 服务器推送到 Heroku 时崩溃

Question

我无法部署到 Heroku。我过去成功地做到了这一点，两个应用程序的基本设置和服务器是相同的。然而，一个失败，一个工作。

很多相关的 StackOverflow 帖子似乎都在谈论 Heroku 分配的服务器端口，但我已经以与我的其他应用程序相同的方式实现了这一点。

干杯。

我的 Proc 文件：

web: node server.js

我的 server.js 文件

var express = require('express');
var http = require('http');   
var socket = require('socket.io');
var path = require('path');
var bodyParser = require('body-parser');
var app = express();
var server = http.createServer(app);
var io = socket.listen(server);



app.get('/', function(request, response) {
  var ua;
  ua = request.headers['user-agent'];
  if (/mobile/i.test(ua)) {
    app.use(express["static"](path.join(__dirname, '')));
    return response.sendfile(__dirname + "/mobile.html");
  } else {
    app.use(express["static"](path.join(__dirname, '')));
    response.sendfile(__dirname + "/index.html");
  }
});


...stuff here related to Socket.io


var port = Number(process.env.PORT || 8080);
server.listen(port, function() {
  return console.log('listening on ' + port);
});

更新

由于某种原因，没有运行网络测功机。我缩放到 1，然后得到了这个崩溃日志

Answer 1

问题是我在 devDependencies 中添加了 express，而不是依赖项。
