어떤 이유로 서버에 간단하게 연결할 수 없습니다. 기본 설정으로 Node.JS와 함께 최신 MySQL Community 8.0 데이터베이스를 설치합니다.

이것은 내 node.js 코드입니다

    var mysql = require('mysql');

    var con = mysql.createConnection({
      host: "localhost",
      user: "root",
      password: "password",
      insecureAuth : true
    });

    con.connect(function(err) {
      if (err) throw err;
      console.log("Connected!");
    });

아래는 명령 프롬프트에서 발견 된 오류입니다.

C:\Users\mysql-test>node app.js
    C:\Users\mysql-test\node_modules\mysql\lib\protocol\Parse
    r.js:80

https://github.com/mysqljs/mysql/issues/1507 과 같은 것들을 읽었습니다.

그러나 여전히 내 문제를 해결하는 방법을 모르겠습니다. 도움을 주시면 감사하겠습니다 .D
