TypeError：Router.use（）需要中间件函数，但得到一个Object IN Node js

Question

我在本地主机上设置应用时遇到此错误。 “Router.use（）需要中间件功能，但需要一个Object”。  请看一下解决这个问题。

../master/node_modules/express/lib/router/index.js:458

            ^

我的app.js文件。

 'use strict';

 import express from 'express';
 import mongoose from 'mongoose';
 mongoose.Promise = require('bluebird');
 import config from './config/environment';
 import http from 'http';

 // Connect to MongoDB
 mongoose.connect(config.mongo.uri, config.mongo.options);
 mongoose.connection.on('error', function(err) {
     console.error('MongoDB connection error: ' + err);
     process.exit(-1);
 });

 // Populate databases with sample data
 if (config.seedDB) {
     require('./config/seed');
 }

 // Setup server
 var app = express();
 var server = http.createServer(app);
 var socketio = require('socket.io')(server, {
     serveClient: config.env !== 'production',
     path: '/socket.io-client'
 });
 require('./config/socketio').default(socketio);
 require('./config/express').default(app);
 require('./routes').default(app);

 // Start server
 function startServer() {
     app.angularFullstack = server.listen(config.port, config.ip, function() {
         console.log('Express server listening on %d, in %s mode', config.port, app.get('env'));
     });
 }

 setImmediate(startServer);

 // Expose app
 exports = module.exports = app;

我的routes.js文件。

'use strict';

import errors from './components/errors';
import path from 'path';
import aws from './api/config/aws.js';

export default function(app) {
    // Insert routes below
    app.use('/api/reports', require('./api/report'));
    app.use('/api/utilities', require('./api/utility'));
    app.use('/api/mails', require('./api/mail'));
    app.use('/api/repayments', require('./api/repayment'));
    app.use('/api/transactions', require('./api/transaction'));
    app.use('/api/offers', require('./api/offer'));
    app.use('/api/payments', require('./api/payment'));
    app.use('/api/yelp', require('./api/yelp'));
    app.use('/api/blogs', require('./api/blog'));
    app.use('/api/faqs', require('./api/faq'));
    app.use('/api/blog', require('./api/blog'));
    app.use('/api/listings', require('./api/listing'));
    app.use('/api/users', require('./api/user'));
    app.get('/api/s3Policy', aws.getS3Policy);
    app.post('/api/uploadToS3', aws.uploadToS3);

    app.use('/auth', require('./auth'));

    // All undefined asset or api routes should return a 404
    app.route('/:url(api|auth|components|app|bower_components|assets)/*')
        .get(errors[404]);

    // All other routes should redirect to the index.html
    app.route('/*')
        .get((req, res) => {
            res.sendFile(path.resolve(app.get('appPath') + '/index.html'));
        });
}

auth文件夹下有一个Index.js，其中使用了 express.Router（）。

'use strict';

import express from 'express';
import passport from 'passport';
import config from '../config/environment';
import User from '../api/user/user.model';

// Passport Configuration
require('./local/passport').setup(User, config);
require('./facebook/passport').setup(User, config);
require('./google/passport').setup(User, config);

var router = express.Router();

router.use('/local', require('./local'));
router.use('/facebook', require('./facebook'));
router.use('/google', require('./google'));

export default router;
