Client does not support authentication protocol

[Narcis 0]

I try to learn Node.js and the MsQL connection. I follow this tutorial:

https://www.w3schools.com/nodejs/nodejs_mysql.asp

But when I put that in the Mac Terminal:

node demo_db_connection.js

I get that error:

sqlMessage: 'Client does not support authentication protocol requested by server; consider upgrading MySQL client',

sqlState: '08004',

 

I tried many things. Please help.
