安装mongoose不能连接mongoDB一直没找到原因

• 今天在node中安装了mongoose,按照流程连接mongoDB一直报错,在网上查了好多方法,都没有对应的,希望有大佬能给知道一下,不胜感激
  • 连接信息

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/mynode');
var db = mongoose.connection;

• 报错信息

$ node mongoose11.js
F:\studyFile\mongodbData\data\node_modules\whatwg-url\dist\encoding.js:2
const utf8Encoder = new TextEncoder();
                    ^
