PHP 版本 Laravel

Question

Does a Laravel project require 2 versions of PHP?

I am working on a Laravel project. I have 2 versions of PHP in my computer. If I set PHP version 8.1 and run composer update I am getting below error.

If I set PHP version 7.4 and run composer update I am getting below error.

What will be the solution?

On Linux I use update-alternatives . You can do sudo update-alternatives --config php , and after that you can check your default version by PHP -v If it does not work please run these commands:

composer clear-cache
composer self-update
composer update --ignore-platform-reqs

I hope it helps you.
