javascript - The problem of using MongoDb to store session data in Node and Express development. According to the book, the following questions appeared. I have been searching for a long time and cannot find the answer. I would like to ask everyone for advice.

Question

Error using MongoDb to store session data

Code:
// Use mongoDb to store session data

var MongoSessionStore = require('session-mongoose')(require('connect'));
var sessionStore = new MongoSessionStore({url: credentials.mongo.production.connectionString});

app.use(require('cookie-parser')(credentials.cookieSecret));
// store是会话存储的实例，默认为一个MemoryStore的实例
app.use(require('express-session')({ store: sessionStore }));

An error occurred during operation

C:\Program Files\nodejs\projects\meadowlark\node_modules\session-mongoose\index.
js:266
    })(connect.session.Store);
                      ^

TypeError: Cannot read property 'Store' of undefined

    at startup (bootstrap_node.js:150:9)
    at bootstrap_node.js:505:3

I searched Baidu and Google for a long time, and tried require('session-mongoose')(require('express')); and so on, but it still failed. I also tried require('connect-mongo')( require('express'));, I have been confused for a long time, so I specifically asked the experts.
