在app.js中通过foreach添加路由时出现Router.use()抛出错误

当我使用相同的方法时,我陷入了一个在我以前的项目中不是问题的问题。我正在尝试以下方式添加路由和文件路径:

app.use(app.router);

APIRoutes.forEach(function (object) {
    app.use(object.route, require(object.path));
});

一旦我这样做,它就会显示错误

我在以前的项目中也做了同样的工作,他们的工作很好。对于这个问题,我得到的更多见解是,我以前的项目是在express 2.0.0框架中进行的,现在一些组件被删除了。但我没有找到解决办法。

product.js文件

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

var ProductModel = new Schema({
productId: Number,
name: String,
quantity: Number,
price: Number,
activeStatus: Number
});

const Product = mongoose.model('myProduct', ProductModel);
module.exports = Product;
