error creating migration in laravel: 'failed to open stream'

I created my first migration create_users_migration using the command:

php artisan make:migration create_users_table

I later on realized there was an error and so deleted the migration file and decided to create different migration file with the same command above. But it keeps throwing this exception:

[ErrorException]
include(/home/awa/Desktop/intern/train2/vendor/composer/../../database/migr
ations/2014_10_12_000000_create_users_table.php): failed to open stream: No
such file or directory

what am I doing wrong?
