Installation in error with Laravel 9

[foutesting]

Environment :
Windows 10
PHP 8.1.2
Composer : 2.2.6
Node : 16.14.0
Npm : 6.14.5
Laravel : 9
Laravel framework : 9.0.1

When I run the following command on a clean installation :

composer require spatie/laravel-backup

Using version ^7.7 for spatie/laravel-backup
./composer.json has been updated
Running composer update spatie/laravel-backup
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires spatie/laravel-backup ^7.7 -> satisfiable by spatie/laravel-backup[7.7.0, ..., v7.x-dev].
- spatie/laravel-backup[7.7.0, ..., v7.x-dev] require illuminate/console ^8.36 -> found illuminate/console[v8.36.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.

You can also try re-running composer require with an explicit version constraint, e.g. "composer require spatie/laravel-backup:*" to figure out if any version is installable, or "composer require spatie/laravel-backup:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Support for laravel 9 got added in version 8.0.

Try installing using:
composer require spatie/laravel-backup "^8.0"

[foutesting]

composer require spatie/laravel-backup "^8.0"
Response received :

[InvalidArgumentException]
Package spatie/laravel-backup at version 8.0 has requirements incompatible with your PHP version, PHP extensions and Composer version:
- spatie/laravel-backup 8.0.0 requires ext-pcntl * but it is not present.

composer require spatie/laravel-backup "^8.0" Response received :

[InvalidArgumentException] Package spatie/laravel-backup at version 8.0 has requirements incompatible with your PHP version, PHP extensions and Composer version: - spatie/laravel-backup 8.0.0 requires ext-pcntl * but it is not present.

On windows you need to ignore ext-pcntl: composer require spatie/laravel-backup "^8.0" --ignore-platform-reqs

It work ! Thanks a lot

On V7 ext-pcntl was optional

laravel-backup/src/Commands/BaseCommand.php

Lines 17 to 19 in ce99f8a

	if ($this->runningInConsole() && SignalRegistry::isSupported()) {
	$this->handlesSignals[] = SIGINT;
	}

Fixed on 8.0.2
