I also was not able to install the default project. Only some steps helped me. Have you tried a composer upgrade in the project folder?

I also had to run php artisan key:generate because i recieved the No application encryption key has been specified message

The .env file is not creaed.

copy('.env.example', '.env');"

Just make a copy of '.env.example' and rename it to '.env'
