平均网络开发

目前我正在关注名为书的标题。我的代码如下(从书中，据我所知，它完全匹配(。如果这是我可以轻松搜索的东西，我深表歉意，但我老实说，我不太了解其他答案，无法弄清楚。检查并重新检查书中的代码以及我所拥有的内容，我没有看到我犯的任何错误。

我正在使用的MEAN Stack(我不知道不止一个(是MongoDB Express AngularJS和Nodejs

错误消息(对不起，我不敢相信我最初忘记了这个(

e:'MEAN'node_modules'mongoose'lib'index.js:323
    throw new mongoose.Error.MissingSchemaError(name);
        ^
MongooseError: Schema hasn't been registered for model "User".

如果有任何区别，那就是目录结构

app/
    controllers/
        users.server.controllers.js
    models/
        user.server.model.js
    routes/
        users.server.routes.js
config/
    express.js
    mongoose.js

快递.js

var config = require('./config'), 
express = require('express'),
morgan = require('morgan'),
compress = require('compression'),
bodyParser = require('body-parser'),
methodOverride = require('method-override'),
session = require('express-session');
module.exports = function () {
    var app = express();
    if (process.env.NODE_ENV === 'development') {
        app.use(morgan('dev'));
    } else if (process.env.NODE_ENV === 'production') {
        app.use(compress());
    }
    app.use(bodyParser.urlencoded({extended:true}));
    app.use(bodyParser.json());
    app.use(methodOverride());
    app.use(session({
        saveUninitialized: true,

    app.set('views', './app/views');

    app.use(express.static('./public'));
    return app;
};
