所以，我无法连接到MongoDB(Atlas(。我觉得我在这里可能快疯了，因为原木就像沉船上的锚一样有用。事情是这样的。谢谢你的帮助
这是我的server.js文件：
'use strict';
const mongodb = require('mongodb');
const http = require('http');
const nconf = require('nconf');
let uri = 'mongodb://USERNAME:PASSWORD@cluster0-w4hci.mongodb.net/test?retryWrites=true&w=majority;';
以下是控制台所说的内容
npm start
> test@1.0.0 start /home/XXXXXXX
> node server.js
mongodb://USERNAME:PASSWORD@cluster0-w4hci.mongodb.net/test?retryWrites=true&w=majority;
/home/XXXXXXX/node_modules/mongodb/lib/mongo_client.js:421
throw err
^

发现我的node.js驱动程序与我想象的版本不同。一旦我从Atlas中选择了正确的版本，URI就工作了，我没有连接！
