Installation on XAMPP error "continue" targeting switch is equivalent to "break"

I am trying to install df 2 on xampp ( OS win 10 64 bit, PHP 7.3.3, mysql database ), clone from the Git repo.
But when running df:setup, I got this error :

Running Seeder…
Seeding: AppSeeder
“continue” targeting switch is equivalent to “break”. Did you mean to use “continue 2”?

Please help how to solve this issue
