Answer 1

It's possible it won't work with PHP8. However, if you'd like to try, use the flag "--ignore-platform-reqs" on your install.

Answer 2

use the below command:

composer install --ignore-platform-reqs

and update your composer.json file PHP version and platform-check:

"platform-check": false,

"require": {
  "php": ">=8.0.2",
  "roots/acorn": "^2.0"
}
