嗨，朋友们！
我正在尝试连接node.js项目与mongodb，我开始与mongodb atlas和它的工作正常，但当我尝试与mongodb指南针没有工作！我不知道发生了什么，但我会张贴我的node.js代码与终端和mongod的结果CMD和指南针捕获

节点. JS代码

const joi = require('joi')
const express = require('express')
const app = express()
const port = 3000
const mongoose = require('mongoose');
const { string } = require('joi');
const dataBaseLink = `mongodb://localhost:27017/myapp`;
 mongoose.connect(dataBaseLink, {useNewUrlParser: true})
.then(result =>{
  app.listen(port, () => {
    console.log('Connected Successfully');
    console.log(`Example app listening on port ${port}`)
  })})
.catch(err => {
  console.error("Connection problem, please try again!.");});

最终结果

经过一些研究，我在MongoDB开发人员社区发现了这一点：

**您的连接被拒绝消息表示已尝试通过IPv6本地主机别名：：1（0：0：0：0：0：0：0：1）进行连接。

默认情况下，mongod不绑定到IPv6地址：则必须将net.ipv6设置为true并在net. bindIp中添加适当的IPv6地址。
如果您使用的是默认mongod配置，则应该能够连接到localhost：27017或等效的IPv4地址127.0.0.1：27017。**
我希望这对遇到类似问题的人有帮助。
