Sounds like you don’t have the SQLite PHP extension installed. Please review the CodeIgniter 4 server requirements.

I have according to my xampp file "phpinfo.php"
It says
PDO Driver for SQLite 3.x: Enabled
SQLite Library: 3.24.0

I am on PHP 7.3.5, Codeigniter 4.0.2 and I have installed Myth/auth today.

Sometimes the database error occurs if a Composer installation fails. Can you verify if you install via Composer? Also make sure you are viewing phpinfo.php from the command line since PHP often runs different versions from browser and CLI, and you need spark to have access to the extension.

MGatner, I have now installed SQLite and still get the following error when I run "php spark migrate -all":
CodeIgniter CLI Tool - Version 4.0.2 - Server-Time: 2020-04-13 03:43:26am

Running all new migrations...
An uncaught Exception was encountered

Type: Error
Message: Class 'SQLite3' not found
Filename: C:\xampp\htdocs\ci4i\vendor\codeigniter4\framework\system\Database
SQLite3\Connection.php
Line Number: 89

agungsugiarto: Thank you. I might try it as a Plan B.

I temporarily renamed the Test folder and run "php spark migrate -all". Now I got the this message:
CodeIgniter CLI Tool - Version 4.0.2 - Server-Time: 2020-04-13 03:48:18am

PHP Fatal error: Cannot declare class Myth\Auth\Commands\CreateGroup, because t
he name is already in use in C:\xampp\htdocs\ci4i\vendor\myth\auth\src\Commands
CreateGroup.php on line 49

And when I now check my db I have 16 Myth tables. Maybe they was migrated the first time I run the command and got the SQLite error. I don't know.

Anyway, time to move on.

In php.ini uncomment the following lines does solve the issue for me.

extension=sqlite3
extension=pdo_sqlite

I myself just ran into this issue and solved it by running 2 commands

sudo apt install php7.2-sqlite
sudo systemctl restart apache2

hope it helps!
