我正在关注 Udemy 的 MERN Stack 教程，我正在尝试将 mongodb 与 mongoose 连接起来。我配置的代码在这里：

(db.js)

const mongoose = require('mongoose');
const config = require('config');
const db = config.get('mongoURI');

const connectDB = async () => {
  try {
    await mongoose.connect(db);

    console.log('MongoDB Connect...');
  } catch (err) {
    console.error(err.message);
    //Exit process with falure
    process.exit(1);
  }
};

module.exports = connectDB;

(server.js)

const express = require('express');
const connectDB = require('./config/db');

const app = express();

//connect database
connectDB();

app.get('/', (req, res) => res.send('API Running'));

const PORT = process.env.PORT || 5000;

app.listen(PORT, () => console.log(`Server started on port ${PORT}`));

（包.json）

{
  "name": "devconnect",
  "version": "1.0.0",
  "description": "Social Network for Developers",
  "main": "server.js",
  "scripts": {
    "start": "node server",
    "server": "nodemon server"
  },
  "author": "Jason Thomas",
  "license": "MIT",
  "dependencies": {
    "bcryptjs": "^2.4.3",
    "config": "^3.2.5",
    "express": "^4.17.1",
    "express-validator": "^6.3.1",
    "gravatar": "^1.8.0",
    "jsonwebtoken": "^8.5.1",
    "mongoose": "^5.8.9",
    "request": "^2.88.0"
  },
  "devDependencies": {
    "concurrently": "^5.0.2",
    "nodemon": "^2.0.2"
  }
}

输入 [npm run server] 后这是我的错误信息

Server started on port 5000
Password contains an illegal unescaped character
[nodemon] app crashed - waiting for file changes before starting...

我无法弄清楚这一点，我知道它很简单，我做错了什么，我该如何解决这个问题？

最好的问候和谢谢

如果你有相同的文件夹结构，你应该有一个像这样的 config/default.json，包含你从 mongoDB 集群连接设置中复制粘贴的字符串：

{
  "mongoURI": "mongodb+srv://username:<password>@devconnector-clusterid.mongodb.net/somethingSomething?retryWrites=true",
  "jwtSecret": "secret",
  "githubClientId": "",
  "githubSecret": ""
}

输入密码时请务必删除字符 < >。

新课程的所有文件都在这里 - Devconnector 2.0在旧版本的课程中，它是 config/keys.js 。

我一开始也犯了同样的错误。在 MongoDB URI 链接中删除“{}”
