    It seems that the composer is using an old PHP version on your system, try to reconfigure it using this command:

    composer config platform.php 7.4.3

    This error comes due to compatible version in your composer.json file. To permanently fix this issue, change the composer.json file “platform” configuration:

    "platform": {
            "php": "7.4.3"
 }

    Then execute composer install

    I had this error with some other package installations on my local version (my local php version differed from the one on server) so I just ran:

    composer require "some/other-package:^1.0" --ignore-platform-reqs

    and all is fine now.

    if being supposed to install "laravel/ui"
    naturally it would claim for matching php version because current ui level is 3.3.0 and php’s is 8.0.2 (or so, not sure). Thus what you re going to console next is:

    composer update      //in case you corrupted something 
composer require laravel/ui:^3.3.0
