node.js – Heroku说：找不到模块’socket.io’

我正在部署一个带有deps / modules的node.js应用程序,例如：heroku上的stylus,express,socket.io.

server.js的开头

/**
 * Bootstrap app.
 */

// I've tried with and without that line... not sure what it does
require.paths.unshift(__dirname + '/../../lib/');



/**
 * Module dependencies.
 */

// I've tried with "socket.io","./socket.io" and "Socket.IO"
var express = require('express'),stylus = require('stylus'),nib = require('nib'),sio = require('socket.io');

文件package.json

{
“name”: “test.io”,“description”: “blabla”,“version”: “0.0.1”,“dependencies”: {
“express”: “2.3.11”
,“jade”: “0.12.1”
,“stylus”: “0.13.3”
,“nib”: “0.0.8”
} }

所以唯一的heroku网络工作者崩溃.这是日志：

那么,有什么想法吗？有没有发生过任何人？

解决方法

我相信你应该在package.json中的依赖项中添加socket.io.

{ "name": "test.io","description": "blabla","version": "0.0.1","dependencies": { "express": "2.3.11","jade": "0.12.1","stylus": "0.13.3","nib": "0.0.8","socket.io" : "0.8.5" } }

或者只是这样做：

npm install socket.io –save

这将安装最新版本的socket.io并将其添加到依赖项中.
