我正在尝试部署到Heroku。构建完成，但在尝试访问应用程序的已部署Heroku URL时，我遇到了可怕的应用程序错误页面。为了记录，应用程序在本地工作正常。

我检查了以下错误行：
Error: Cannot find module 'connect-livereload'
所以我尝试 npm安装connect-livereload 无济于事。
我以为我也会分享我的app.js文件：
'use strict';
// Set default node environment to development
process.env.NODE_ENV = process.env.NODE_ENV || 'development';
var express = require('express');
var mongoose = require('mongoose');
var config = require('./config/environment');
// Connect to database
mongoose.connect(config.mongo.uri, config.mongo.options);
// Populate DB with sample data
if(config.seedDB) { require('./config/seed'); }
// Setup server
var app = express();
var server = require('http').createServer(app);
var socketio = require('socket.io')(server, {
serveClient: (config.env === 'production') ? false : true,
path: '/socket.io-client'
});
require('./config/socketio')(socketio);
require('./config/express')(app);
require('./routes')(app);
// Start server
server.listen(config.port, config.ip, function () {
console.log('Express server listening on %d, in %s mode', config.port, app.get('env'));
});
// Expose app
exports = module.exports = app;
不知道还能转向何处。如果有人能指出我正确的方向，我们将不胜感激......

我使用以下yeoman生成器来构建应用程序：
https://github.com/DaftMonk/generator-angular-fullstack
所以我尝试在该链接上使用heroku部署指令，这导致了一些构建错误，但最终能够按照说明修复这些错误。现在部署工作，所以这不再是一个问题。
