Node connection Mysql error ER_NOT_SUPPORTED_AUTH_MODE

My system is installed with the mysql-installer-community-8.0.18.0.msi version, and then I use node-mysql locally to connect to the database.

var mysql  = require('mysql');  
 
var connection = mysql.createConnection({     
  host     : 'localhost',     //本机地址
  user     : 'root',          //用户
  password : '123456',        //密码
  port: '3306',               //端口号
  database: 'test'            //要连接的数据库
}); 
 
connection.connect();
 
var  sql = 'SELECT * FROM table1';   //查询table1表的所有数据

connection.query(sql,function (err, result) {
        if(err){
          console.log('[SELECT ERROR] - ',err.message);
          return;
        }
 
       console.log('--------------------------SELECT----------------------------');
       console.log(result);
       console.log('------------------------------------------------------------\n\n');  
});
 
connection.end();

run node test.js

Execute the following results:

F:\All Project\test\node>node test.js

solution

1. Enter the terminal to log in to mysql, use the name mysql -uroot -p and then enter the password and enter the mysql password to enter. Note the spaces

2. After entering the password, this page will appear

3. Import instruction: alter user 'root'@'localhost' identified with mysql_native_password by '123456';

Change the password after the last by in the first paragraph to your own password and press Enter to execute
