我正在尝试使用 mongodb 所以我安装了 mongoose 包

但问题是当我这样写的时候

const express = require("express");
const dotenv = require("dotenv");
const mongoose = require("mongoose"); //getting error here

它向我显示这样的错误

const utf8Encoder = new TextEncoder();
                    ^

ReferenceError: TextEncoder is not defined

如果我评论 mongoose 行，我不会收到任何错误，但即使我检查了我的节点版本为 16.5.0，我也需要使用它，我尝试查找发生相同错误的旧帖子，但它对我来说无法理解，有什么帮助吗？旧帖子链接 在此处输入链接描述

如何修复此错误

问题似乎出在 mongoose 和 mongodb 包上，因为它在以下情况下工作正常

mongoose.connect('mongodb+srv://mydb:<password>@cluster0.w1opr.mongodb.net/test?retryWrites=true&w=majority');

被删除它在 repl.it 云环境上也可以正常工作这是我的代码

var express = require('express');
var ejs = require('ejs');
var app = express();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
mongoose.connect('mongodb+srv://mydb:<password>@cluster0.w1opr.mongodb.net/test? 
retryWrites=true&w=majority');
app.set('view engine','ejs')
app.use(bodyParser.urlencoded({extended: true}));
.
.
.
app.listen(3000,function(){
console.log('Server is running on port 3000');
});

我有这两个文件：

测试.js：

const jsdom = require("jsdom");

const hello  = () =>  {
  console.log("hello!");
};


module.exports = {
    hello
};

和

服务器.js：

const hello = require('./stuff/test');

hello.hello();

目录结构：

myprojectfolder
             backend
                    src
                       stuff
                           test.js
                       server.js

当我运行时，server.js我收到ReferenceError: TextEncoder is not defined错误：

/home/myusername/projects/myprojectfolder/node_modules/whatwg-url/lib/encoding.js:2
const utf8Encoder = new TextEncoder();
                    ^

ReferenceError: TextEncoder is not defined

如果我const jsdom = require("jsdom");从 中删除行test.js，server.js则运行正常并且没有任何错误（输出hello）。

为什么会发生这种情况以及如何修复它（同时仍然能够jsdom在内部导入和使用test.js？）。

我在尝试学习如何测试 next.js 应用程序时收到此错误消息我尝试从配置顶部的 utils 导入文本编码器以及测试文件，但没有成功

  ReferenceError: TextEncoder is not defined
