There are a few steps you can take to fix the "driver not found error" in Symfony and PostgreSQL.

  1. Make sure you have the correct driver installed: Check if you have the pdo_pgsql driver installed for PostgreSQL. You can verify this by running php -m in your command line and checking if pdo_pgsql is listed. If it is not listed, you need to install it.
  2. Install the missing driver: If you are using Linux, you can install the missing driver by running the following command: sudo apt-get install php-pgsql If you are using Windows, you can enable the driver by uncommenting the following line in your php.ini file: extension=pdo_pgsql Then, restart your server.
  3. Update your Symfony configuration: Open your config/packages/doctrine.yaml (or config/packages/doctrine.yaml.dist) file and ensure that the following lines are present: doctrine: dbal: driver: 'pdo_pgsql' server_version: '13' # Replace with the appropriate PostgreSQL version
  4. Clear the cache: Run the following command to clear the Symfony cache: php bin/console cache:clear
  5. Verify the connection: Test your connection by running the following command: php bin/console doctrine:database:connect If you see a successful connection message, then the "driver not found" error should be resolved.


If you have followed these steps and are still encountering the error, it is possible that there may be other underlying issues with your setup. In that case, you might need to seek further assistance or consult the Symfony and PostgreSQL documentation for troubleshooting specific to your environment.
