How to add sqlite to lumen?

I would like to add sqlite db to my lumen app but I have some troubles. I create migration:

php artisan make:migration create_users_table --create=users

then I changed my .env file, so it looks like:

DB_CONNECTION=sqlite
DB_HOST=localhost
DB_DATABASE=database.sqlite

then I was created database.sqlite and put it in storage folder and when I 'm trying to do:

php artisan migrate

I have

[InvalidArgumentException]
Database (database.sqlite) does not exist.

I uncommented this lines:

Dotenv::load(__DIR__.'/../');
$app->withFacades();

I can't find what is wrong.

I work on ubuntu 14.04
