解决方法：

// 进入mysql 输入密码例如：123456
mysql -u root -p 

// 1.执行语句 alter user 'root'@'localhost' identified with mysql_native_password by 密码;
mysql> alter user 'root'@'localhost' identified with mysql_native_password by '123456';
Query OK, 0 rows affected (0.43 sec)

// 2.再执行语句 flush privileges;
mysql> flush privileges;
Query OK, 0 rows affected (0.05 sec)

//3.成功后 退出
mysql> quit
Bye

nodejs环境重启下即可 npm run dev

原因：

MySQL8.0.4之前，MySQL的密码认证插件是

“mysql_native_password”，而以后版本使用的是“caching_sha2_password”。所以node会密码认证失败
