node.js - 类型错误 : Cannot read property 'auth' of undefined

Question

我正在使用express和mongoose-auth编写一个node.js应用程序。当我运行我的应用程序时，我会得到一个包含以下堆栈跟踪的网页。

TypeError: Cannot read property 'auth' of undefined

    at HTTPServer. (/home/levi/Projects/Cloudrr/node_modules/mongoose-auth/node_modules/everyauth/lib/expressHelper.js:7:27)
    at ServerResponse._render (/home/levi/Projects/Cloudrr/node_modules/express/lib/view.js:393:58)

    at next (/home/levi/Projects/Cloudrr/node_modules/express/node_modules/connect/lib/http.js:201:15)

这是我的 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"
  }
}

我做错了什么？堆栈跟踪指向第 41 行，该行位于第一条路由的中间。谷歌搜索向我展示了 everyauth 问题跟踪器中的几个问题，这些问题具有相同的错误，但没有一个解决方案提供工作。感谢您抽出时间。

我相信您缺少一个必需的步骤，请参阅 mongoose-auth documentation 中的架构装饰.

你可能和我几周前所在的地方一样。如果您当前的应用程序是新的，因此仍然很小，您可能需要使用 mongoose-auth 示例程序启动一个新项目。验证您可以登录和注销后，您可以添加您的应用程序功能。
