Hi,

Trying to install codecept file with Composer

And I have this

D:\OpenServer\domains\opensource.php>composer require "codeception/codeception:*"
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
31 packages you are using are looking for funding.

@php requirements.php

Fatal error: Uncaught PDOException: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) in D:\OpenServer\domains\opensource.php\vendor\yiisoft\yii2\db\Connection.php:705
