我正在尝试完成本教程：
http://www.thinkster.io/angularjs/GUIDJbpIie/angularjs-tutorial-learn-to-build-modern-web-apps
它使用此处找到的mean-stripdown repo：
https://github.com/msfrisbie/mean-stripdown
但是当我在运行node server后尝试运行npm install时，我收到以下错误：
Error: Most middleware (like session) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.
我认为这是由于Express 4所以我将依赖项中的"express": "latest"更改为"express": "3.x"
现在，当我运行node server时，我在控制台中收到以下内容：
jamesontrinker@jamesons-imac ~/projects/mean-stripdown (master)*$ node server
connect deprecated multipart: use parser (multiparty, busboy, formidable) directly
node_modules/express/node_modules/connect/lib/middleware/bodyParser.js:56:20
connect deprecated limit: Restrict request size at location of read node_modules/express/node_modules/connect/lib/middleware/multipart.js:86:15
connect deprecated methodOverride: use method-override module directly config/express.js:44:21
Express app started on port 3000
events.js:72
throw er; // Unhandled 'error' event
^
Error: failed to connect to [localhost:27017]
这是我的package.json：

和模块依赖关系：
/**
* Module dependencies.
**/
var express = require('express')
, fs = require('fs')
, passport = require('passport')
, logger = require('mean-logger')
非常感谢。
