php voyager没有制作表格

To the best of my knowledge i am setting up php voyager as explained from the download page https://github.com/the-control-group/voyager correctly.

Only i am not succceeding on getting the admin page http://localhost:8000/admin.

Trying to understand the problem i keep encountering that during installation i am to have at least one more table called roles. Googling around i even saw there are infact several other tables voyager apparently sets up.

The only table i got in my installation was users. and even that refused to populate with dummy data even though i had used the command

php artisan voyager:install --with-dummy

I have not seen on the web or SO anyone else with this complain or challenge so can someone please help out a brother?

When i run

 php artisan serve

something tells me the server is running okay but instead of admin panel for voyager i get error 404 page cannot be found.

I have tried several times repeating the process even uninstalling and reinstalling wamp64 3.1.4 but i am always ending up the same place. In use is windows 10 on 64 bit machine.

The only thing i can point at as being unusual is that on my green wamp icon following and clicking on php7.2.10 php.ini gives the message "The parameter is incorrect" and i get the same message Parameter is incorrect when i follow and click on php7.2.10 PHP error log

Who knows what i can try?
