Class 'Doctrine\DBAL\Driver\PDOSqlite\Driver' not found

This error typically occurs when the Doctrine DBAL library is unable to locate the PDOSqlite driver class. It could be due to a missing or improperly configured dependency.

To fix this issue, you can follow these steps:

1. Make sure you have installed the Doctrine DBAL library in your project. You can add it to your composer.json file and run composer update:

   "require": {
       "doctrine/dbal": "^2.13"
   }
   

2. Ensure that the pdo_sqlite extension is installed and enabled in your PHP configuration. You can check this by running php -m in your command line and verifying that pdo_sqlite appears in the list of loaded modules. If it's not enabled, you can enable it by uncommenting the line extension=pdo_sqlite in your php.ini file.

3. If you are using a framework or a third-party package that manages dependencies, make sure that the Doctrine DBAL library and the pdo_sqlite extension are correctly configured and loaded by the framework.

Once you have resolved the underlying cause of the error, you should no longer encounter the Class 'Doctrine\DBAL\Driver\PDOSqlite\Driver' not found error.
