Fixing the exception of php artisan migrate:rollback

The correction of this small obstacle is very simple, and very common in the day-to-day development with Laravel and the autoloadings of PSR-4 created and organized by Composer.

The cause is most of the time the lack of updating the Autoad File generated by the composer. For several reasons this can happen.

To correct, perform the composer’s Autoloading Dump on the terminal’s command line in the root directory of your project:

composer dump-autoload

If the problem persists, first clean the compilation cache generated by the previous Dump and run the command again:

php artisan clear-compiled
composer dump-autoload

If the compiled cache is not updated, it may be necessary to manually delete the file vendor/compiled.php and then perform the steps above again.

php artisan migrate:rollback without errors

After the autoader updates and cache cleaning performed, the expected result:

php artisan migrate:rollback
