Can’t install Sylius starter project

I’d like to create a Sylius project but I can’t install the initial project following the instructions in the documentation.

the command compose

compose create-project sylius/sylius-standard MyFirstShop

works but when I create .env.local which contains :

DATABASE_URL=mysql://root@localhost/my_project?serverVersion=8

then I run the command :
php bin/console sylius:install this is where the installation crashes.

I have the following error :

no database error

then I create the database on phpmyadmin then I re-run the command with the database created but empty:

I tried to launch the creation of the database with doctrine and then do the migration but still the same as the image above.

Someone who has already had the same problem 🙁
