TypeError：無法讀取未定義的屬性'auth'

我正在使用express和mongoose-auth編寫node.js應用程序。當我運行我的應用程序時，我得到一個帶有以下堆棧跟蹤的網頁。TypeError：無法讀取未定義的屬性'auth'

TypeError: Cannot read property 'auth' of undefined

這裏是我的app.js：

/** 
* Module dependencies. 
*/ 

var express = require('express'); 
var mongoose = require('mongoose'); 
var mongooseAuth = require('mongoose-auth'); 
var model = require("./models"); 
var app = module.exports = express.createServer(); 

// Configuration 

app.configure(function(){ 
    app.set('views', __dirname + '/views'); 
    app.set('view engine', 'jade'); 
    app.use(express.bodyParser()); 
    app.use(express.methodOverride()); 
    app.use(app.router); 
    app.use(express.static(__dirname + '/public')); 
    app.use(mongooseAuth.middleware()) 
}); 

app.configure('development', function(){ 
    app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); 
}); 

app.configure('production', function(){ 
    app.use(express.errorHandler()); 
}); 
// Database 

var Proffile = mongoose.model('Profile', model.Profile); 
var Cloudrr = mongoose.model('Cloudrr', model.Cloudrr); 
var Cloud = mongoose.model('Cloud', model.Cloud); 
var User = mongoose.model('User', model.UserSchema); 
mongoose.connect('mongodb://localhost/cloudrr'); 
// Routes 

app.get('/', function(req, res){ 
    res.render('index', { 
    title: 'Cloudrr | Lorem ipsum' 
    }); 
}); 
app.get('/index', function(req, res){ 
    res.render('index', { 
    title: 'Cloudrr | Lorem ipsum' 
    }); 
}); 
app.get('/left', function(req, res){ 
    if(req.loggedIn == True) 
    { 
     Profile.findById(req.user, function(user){ 
     res.render('left', { 
      title: "Welcome back!", 
      user_id: user.profileID, 
      avatar: user.avatar, 
      followers: user.followers.length(), 
      following: user.following.length(), 
     }); 
     }); 
    } 
    else 
    { 
    res.render("left", { 
     title: "you need to log in." 
    }); 
    } 
}); 

mongooseAuth.helpExpress(app); 
app.listen(3000); 
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);

和的package.json。

{ 
    "name": "cloudrr" 
    , "version": "0.0.1" 
    , "private": true 
    , "dependencies": { 
     "express": "2.4.6" 
    , "jade": ">= 0.0.1" 
    , "mongoose": ">= 2.1.3" 
    , "mongoose-types": ">= 1.0.3" 
    , "mongoose-auth": ">= 0.0.11" 
    } 
}

我在做什麼錯？堆棧跟蹤指向位於第一條路線中間的第41行。谷歌搜索在everyauth問題跟蹤器中向我展示了幾個具有相同錯誤的問題，但沒有提供任何解決方案。感謝您的時間。

您可以通過編輯堆棧頂部的文件'expressHelper.js'並在拋出異常的方法中插入'調試器'語句來自己追蹤。然後使用內置的節點調試器或像node-inspector（我選擇的調試器）這樣的工具來檢查狀態和調用路徑，以查看問題出在哪裏。 – broofa
