Installing Laravel outputs error 255 (detailed in text)

Question

For the first time I am trying to run my Laravel project on newly Arch Linux machine and when running composer require laravel/installer command I get this error:

This is how my composer.json file looks like:

Already tried recommended solutions in these two topics, none of them worked:

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code -1073741819.

Script @php artisan package:discover handling the post-autoload-dump event returned with error code 255.

EDIT: Changing laravel/framework version to ^8.75 did not solve issue as someone flagged this question as duplicate. Instead it outputted new error:

Loading composer repositories with package information
Info from https://repo.packagist.org: #StandWithUkraine
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

Problem 1
- laravel/ui[v2.2.0, ..., v2.4.1] require php ^7.2.5 -> your php version (8.1.5) does not satisfy that requirement.
- illuminate/support[v7.0.0, ..., v7.28.4] require php ^7.2.5 -> your php version (8.1.5) does not satisfythat requirement.
- Only one of these can be installed: illuminate/support[v5.5.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev], laravel/framework[v8.75.0, ..., 8.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
- laravel/ui[v2.5.0, ..., 2.x-dev] require illuminate/support ^7.0 -> satisfiable by illuminate/support[v7.0.0, ..., 7.x-dev].
- Root composer.json requires laravel/ui ^2.2 -> satisfiable by laravel/ui[v2.2.0, ..., 2.x-dev].
- Root composer.json requires laravel/framework ^8.75 -> satisfiable by laravel/framework[v8.75.0, ..., 8.x-dev].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

i would check the php version you have, perhaps an older php 5 for example — Lk77, Apr 27 '22 at 15:55
Laravel 7 isn't compatible with PHP 8.1. It does work with PHP 8.0, as shown by the composer requirements. — aynber, Apr 27 '22 at 15:57
@aynber composer is using PHP version 8.1.5, but I have installed both - 8.1.5 and 7.3. How can I change what PHP version composer uses? Or how can I just downgrade PHP 8.1 to 8.0? — r problems, Apr 27 '22 at 15:59
Downgrading will require installing php 8.0 and making sure everything is pointed to the correct version. https://stackoverflow.com/questions/43040685/how-can-i-change-php-cli-version-on-ubuntu-14-04 has instructions on how to change the PHP version on the command line. Just change the version number from what the accepted answer has. — aynber, Apr 27 '22 at 16:01
@aynber it does not work. Already edited my post and added the output to the bottom. — r problems, Apr 27 '22 at 16:03
There are a lot more changes to make to your composer if you're upgrading from 7 to 8, which that answer does not address. See https://laravel.com/docs/8.x/upgrade for all of the changes — aynber, Apr 27 '22 at 16:06
@aynber I am not trying to upgrade anything, I just want to run older Laravel 7.4x project on my laptop — r problems, Apr 27 '22 at 16:09
Changing the `laravel/framework` to `^8.75` *is* an upgrade. I would suggest running it with PHP 7.4, which my other link addressed for the command line. You'll also need to make sure your web server is using the correct version. — aynber, Apr 27 '22 at 16:10
@aynber I have installed php73 as well, but my composer is running on 8.1.5 according to `composer diagnose` `PHP version: 8.1.5 PHP binary path: /usr/bin/php`. Did not find a way to change binary path do `/usr/bin/php73` where my PHP 7.3 is installed. I need to run this project only on local machine. — r problems, Apr 27 '22 at 16:14
