I'm trying to install this pakage on a Laravel 5.6 and i'm encountering some warnings and errors :

• A lot of "Ambiguous class resolution" warnings
• the following error :

[ErrorException] file_get_contents(/var/www/totem.fftp/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/vendor/jackkum/phppdu/PDU.php): failed to open stream: No such file or directory
