Change laravel version

I was looking though the demo site and I noticed that when you try to click on laravel it only supports 10 up, I have a laravel application that has 9. How can I change that

Just follow installation guide from your project.

Quick install will only install the empty frame work…

Thanks. I just uploaded my application onto it but how do i do composer install. Found this but dont really understand it. Composer to install Apiato

Specifically on how i ssh into that user and how to run composer install

v-add-user-composer user

Says composer us already installed for that user

I get a Class “Maatwebsite\Excel\Excel” not found when visiting the site i added And it was working on the cpanel hosting it was on before
