调用函数时使用mysqljs/mysql作为

npm install --save-dev mysql

我得到以下错误和跟踪。

我的示例代码是

import { APIGatewayEvent, Callback, Context, Handler } from 'aws-lambda';
import {createConnection, Connection} from 'mysql';

export const index: Handler = (event: APIGatewayEvent, context: Context, cb: Callback) => {
  let connection = createConnection({
    host: process.env["DB_RO_HOST"],
    user: process.env["DB_RO_USERNAME"],
    password: process.env["DB_RO_PASSWORD"],
    database: process.env["DB_RO_NAME"]
  });

  connection.connect();

  const response = {
    statusCode: 200,
    body: JSON.stringify("{\"test\":\"test\"}"),
  };

  cb(null, response);
}

当我试图调用connect（）方法时，代码出错。
我的研究结果是，有几个人说，在旧版本的丑和网页中，要关掉丑中的烂。不过，我正在运行一个现代化的网页包。
