ReferenceError：会话未定义为（＆＃39; connect-mongo＆＃39;）（会话），

Question

我尝试添加connect-mongo以便在nodeJS重新启动时保存会话。

根据我添加的文档： MongoStore = require('connect-mongo')(session),

在我的require('express-session')我添加了

store: new MongoStore({
    url: mongooseDB,
    touchAfter: 24 * 3600
})

并注释掉app.use(passport.session());

我收到错误：ReferenceError：未定义会话，指向MongoStore = require('connect-mongo')(session),

我已添加了我的app.js文件以供参考。我该如何解决这个问题？

    app = express(),
    bodyParser = require('body-parser'),
    mongoose = require('mongoose'),
    MongoStore = require('connect-mongo')(session),

const indexRoute = require('./routes/index'),
    usersRoute = require('./routes/users'),
    giftsRoute = require('./routes/gifts.js'),
    searchRoute = require('./routes/search');

const mongooseDB = 'mongodb://localhost/giftcashing';

mongoose.connect(mongooseDB);

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

app.use(logger('dev'));
app.use(bodyParser.urlencoded({extended: true}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/bower_components',  express.static(__dirname + '/bower_components'));

app.use(flash());

app.use(require('express-session')({

    resave: false,
    saveUninitialized: false,
    store: new MongoStore({
        url: mongooseDB,
        touchAfter: 24 * 3600
    })
}));

// PASSPORT CONFIGURATION
app.use(passport.initialize());
// app.use(passport.session());

// use static authenticate method of model in LocalStrategy
passport.use(new LocalStrategy(User.authenticate()));

// use static serialize and deserialize of model for passport session support
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

app.use(function (req, res, next) {
    res.locals.currentUser = req.user;
    res.locals.error = req.flash('error');
    res.locals.success = req.flash('success');
    next();
});

// catch 404 and forward to error handler
// app.use(function(req, res, next) {
//   var err = new Error('Not Found');
//   err.status = 404;
//   next(err);
// });

// error handler
app.use(function(err, req, res, next) {
    // set locals, only providing error in development
    res.locals.message = err.message;
    // render the error page
    res.status(err.status || 500);
    res.render('error');
});

app.use('/', indexRoute);
app.use('/users', usersRoute);
app.use('/gifts', giftsRoute);
app.use('/search', searchRoute);

module.exports = app;

调用时未初始化变量session MongoStore = require('connect-mongo')(session)。

在初始化session = require('express-session')之前添加MongoStore。
