Undefined constant "Spatie\Backup\Commands\SIGINT"

Since 7.3.4 I get this error in the console from composer install/update and any artisan commands.

  Undefined constant "Spatie\Backup\Commands\SIGINT"

I reverted to 7.3.3, and it worked, so I think it may be an issue or conflict.

IIS
PHP 8.0.3
laravel/framework 8.36.2
spatie/laravel-backup 7.4

Edit: This may be because of my Windows (development) environment. PCNTL does not work on Windows and is a requirement from the new upstream spatie/laravel-signal-aware-command.

I have the same issue after upgrading. I'm also running a windows dev environment. I see that Laravel Backup doesnt support windows servers but I'm hopeful theres a fix that allows me to continue using windows to develop even if it can't ultimately take a backup.

Apache (XAMPP)
PHP 8.0.3
laravel/framework 8.36.2
spatie/laravel-backup 7.4

Same here

This particular error is caused by SIGINT not being available on Windows. I'd accept a PR that adds a check for windows to avoid that particular piece of code.

If the fix is not too ugly, I'll consider merging it in 👍

I have encountered the same problem on my forge machine (linux). It happens when I use the Artisan-Facade to call any command.

Reproduction:

1. Add a route to your web.php-file:

use App\Console\Commands\MyCommand;
use Illuminate\Support\Facades\Artisan;

Route::get('/reproduction', function () {
    Artisan::call(MyCommand::class);

    return '👀';
});

2. Visit /reproduction with your browser.

3. Following exception is thrown:
   Undefined constant "Spatie\Backup\Commands\SIGINT"

Having also the same problem in our CI, running composer in the composer:2 docker container.

For those who got the same error, since linux php alpine image doesn't have the pcntl package installed: Run docker-php-ext-install pcntl to install this package. @freekmurze it would be cool if there was a check for that.

Feel free to PR improvements!

Hola, yo tengo el mismo problema, la extensión está instalada correctamente y el entorno está en producción con la última versión de Laravel Nova:

[2022-08-13 04:12:13] local.ERROR: Undefined constant "Spatie\Backup\Tasks\Backup\SIGINT" {"userId":1,"exception":"[object] (Error(code: 0): Undefined constant "Spatie\Backup\Tasks\Backup\SIGINT" at /home/*************************/public_html/vendor/spatie/laravel-backup/src/Tasks/Backup/BackupJob.php:148)

Gracias.

I fixed this issue by disabling Signals

$backupJob = BackupJobFactory::createFromArray(config('backup'));

$backupJob->disableSignals();
$backupJob->run();
