InvalidArgumentException in SQLiteConnector.php line 34: Database (homestead) does not exist

Under that line referenced in your error, is the following:

    // Here we'll verify that the SQLite database exists before going any further    // as the developer probably wants to know if the database exists and this    // SQLite driver will not throw any exception if it does not by default.    if ($path === false) {        throw new InvalidArgumentException("Database (${config['database']}) does not exist.");    }

Looking at the comment above the method, it seems that your path is not correctly set. I believe the correct environment variable should be:

DB_DATABASE=database/database.sqlite

instead of

DB_FILE=database/database.sqlite

If not, check your config/database.php file, and look for this section:

    'sqlite' => [        'driver' => 'sqlite',        'database' => env('DB_DATABASE', database_path('database.sqlite')), // this line!        'prefix' => '',    ],

I just noticed also (at least in Laravel version 5.2.29 on a mac) the path must be an absolute path. The weird thing is, for running migrations a relative path will work but the application then fails when trying to access the DB after that
