我有一个Node.js程序，该程序使用root帐户连接到本地MySQL数据库（这不是生产设置）。这是创建连接的代码：

const mysql = require('mysql');

const dbConn = mysql.createConnection({
    host: 'localhost',
    port: 3306,
    user: 'root',
    password: 'myRootPassword',
    database: 'decldb'
});

dbConn.connect(err => {
    if (err) throw err;
    console.log('Connected!');
});

它可以与MySQL 5.7一起使用，但是由于安装了MySQL 8.0，因此在启动Node.js应用程序时出现此错误：

> node .\api-server\main.js

        throw err; // Rethrow non-MySQL errors
        ^

看来根帐户使用了一种新的密码哈希方法：

> select User,Host,plugin from user where User="root";
+------+-----------+-----------------------+
| User | Host      | plugin                |
+------+-----------+-----------------------+
| root | localhost | caching_sha2_password |
+------+-----------+-----------------------+

…但是我不知道为什么Node.js无法连接到它。我已经更新了所有npm软件包，但这仍然是一个问题。

我想保留新的密码哈希方法。我还能继续进行此连接吗？我是否必须等待MySQL Node.js软件包的更新，或者更改自己的设置？
