Passport.js .authenticate() 抛出 TypeError: undefined is not a function

Question

我是新的护照（和一般节点），并一直在使用本教程 (http://mherman.org/blog/2015/01/31/local-authentication-with-passport-and-express-4/#.VczPbTBViko) 将护照身份验证添加到更大的网络应用程序。我想我一直在正确地跟踪事情，但是当我在终端中启动应用程序时，我收到以下错误。

passport.use(new LocalStrategy(Admin.authenticate()));
                                     ^

我检查了 package.json 并且所有相关库似乎都已安装。

这里是相关代码。

来自 app.js：

//connect to db; require models
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/design-data-test');
var Test = require('./models/Tests');
var Question = require('./models/Question');
var User = require('./models/User');
var Option = require('./models/Option');
var Admin = require('./models/Admin');

//require passport
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

var routes = require('./routes/index');

var express = require('express');
var app = express();

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

//passport setup
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);

//config admin
var Admin = require('./models/Admin');
passport.use(new LocalStrategy(Admin.authenticate()));
passport.serializeUser(Admin.serializeUser());
passport.deserializeUser(Admin.deserializeUser());

admin.js：

var mongoose = require('mongoose');
var passportLocalMongoose = require('passport-local-mongoose')

var AdminSchema = new mongoose.Schema({
    username: String,
    password: String
});

AdminSchema.plugin(passportLocalMongoose);

module.export = mongoose.model('Admin', AdminSchema);

这是一个错字。您必须在 admin.js 中使用 module.exports 而不是 module.export。
