无法将 Mongodb 与我的 server.js 连接

Question

错误：抛出新的 error_1.MongoParseError(${optionWord} ${Array.from(unsupportedOptions).join(', ')} ${isOrAre} not supported);

我收到此错误，我的代码是： 服务器.js

const express = require('express');
const cors = require('cors');
const mongoose = require('mongoose');

require('dotenv').config();

const app = express();
const port = process.env.PORT || 5000;

app.use(cors());
app.use(express.json());

const uri = process.env.ATLAS_URI;
mongoose.connect(uri, { useNewUrlParser: true, useCreateIndex: true }
);
const connection = mongoose.connection;
connection.once('open', () => {
  console.log("MongoDB database connection established successfully");
})



app.listen(port, () => {
    console.log(`Server is running on port: ${port}`);
});

我无法将数据库连接到我的服务器

我认为您可以简单地连接此代码 -

mongoose.connect(uri, {
            useNewURLParser: true,
            useUnifiedTopology: true,
        })
        .then(() => console.log("We are ready with database"))
        .catch((err) => console.log(`Database connection error ${err}`));
