Migrations in Laravel are not been placed in 'database\migrations' folder

I'm making a migration in laravel like this:

php artisan make:migration create_tasks_table

and then I get a message from the console like this:

Created Migration: 2017_04_03_002411_create_tasks_table

But when I go to the 'database\migrations' directory there's no .php file related to the migration I made.

Why is this happening?
