laravel/php?? test github question

Hi/morning...

Got a test github laravel app. Has minimal setup/install steps.

The app  --  https://github.com/jijunair/laravel-referral

I'm curious as to what it looks like, so trying to install/run it from
my cloud/Apache.

I'm "guessing" on the install/setup steps from different apps, but I'm
missing something that appears to be basic.

in the dir
 /var/www/html/jijunair
 cd /var/www/html/jijunair
  all the github files are here
    sudo -u www-data composer install
    sudo -u www-data composer require jijunair/laravel-referral
    npm install

however, the "require" cmd... gives
Root package 'jijunair/laravel-referral' cannot require itself in its
composer.json

so.. anyone have any pointers/thoughts?

thanks


As I said, guessing!!
