In my database.php

	'default' => 'mysql',

	'connections' => [

		'sqlite' => [
			'driver'   => 'sqlite',
			'database' => storage_path().'/database.sqlite',
			'prefix'   => '',

		'mysql' => [

If you used php -S or php artisan serve, you need to restart your php built in server after updating .env file. To be sure, clear the cache.
