When attempting to migrate a database using Laravel 5.4 on Ubuntu 14.04 with Plesk 12.5.30 and PHP 7.0, the following exceptions are encountered:

• [Illuminate\Database\QueryException]

  • could not find driver (SQL: select * from information_schema.tables where table_schema = pmaramaldb and table_name = migrations)

• [PDOException]

  • could not find driver

Troubleshooting

The following solutions have been attempted without success:

• Enabling PDO Extension:

  • PDO is already enabled.

• Installing php7.0-mysql:

  • PHP 7.0-mysql is already installed.

• Installing php5-sqlite:

  • PHP 5.5-sqlite is already installed.

• Running composer dump-autoload:

  • Has no effect.

Alternative Solution

Ensure that php7-mysql is installed. Run the following command:

sudo apt install php7.0-mysql

If Automatic Installation is Preferred:

sudo apt install php-mysql
