I just installed VaniloPHP by following the instruction on the documentation with Laravel 9 but Laravel Mix don't install, instead LaravelVite is installed, it's normal ?
Because of that I can’t manage to build app
Laravel 9 migrated completely from Mix to Vite.
If you want to use Mix you can follow the official Guide to migrate manually back to Laravel Mix:
