You have not provide any necessary info, none of the required, no code snippet, no bug report.

As such look over the tests, then reopen.

`<?php

require '../common/vendor/autoload.php'; use ezsql\Database; //test $sql = "select account from user where id=1"; $db= Database::initialize('PDO', ['mysql:host=localhost;dbname=duwell;port=3306','root','root']);

$data=$db->query($sql);

Is there a problem connecting to the database？

[TheTechsTech]

require '../common/vendor/autoload.php';

What is that? Look at the readme.md examples. You are getting the correct error, there is no error. You are using composer autoload wrong.

If that was the case none of the tests would be passing.
