It seems like the error you're encountering is due to an undefined constant SIGINT. This constant is supposed to be defined by the PHP PCNTL extension, which is used for handling process control signals.

To resolve this issue, you should ensure that the PCNTL extension is installed and enabled on your system. Here's how you can check and install the PCNTL extension:

Check if PCNTL is installed: Run the following command in your terminal to check if the PCNTL extension is already installed:
```
php -m | grep pcntl
```
If you see pcntl in the output, the extension is installed. If not, you'll need to install it.
Install PCNTL extension: The installation process for the PCNTL extension varies depending on your operating system.
- For Ubuntu/Debian systems, you can install it using the following command:
```
sudo apt-get install php-pcntl
```
- For CentOS/RHEL systems, use:
```
sudo yum install php-pcntl
```
- For macOS, if you're using Homebrew, you can install it with:
```
brew install [email protected]
brew link --overwrite --force [email protected]
```
  Replace [email protected] with the version of PHP you're using.
- For Windows, the PCNTL extension is not available.
Enable PCNTL extension: After installing, you may need to enable the extension in your php.ini file. Locate your php.ini file (you can find its path by running php --ini), and make sure the following line is uncommented (remove the ; at the beginning if it's there):
```
extension=pcntl
```
Restart your web server: After enabling the extension, you'll need to restart your web server for the changes to take effect.

For Apache:
```
sudo service apache2 restart
```
For Nginx:
```
sudo service nginx restart
```
For PHP's built-in server, just stop and start it again.
Try running the command again: Once the PCNTL extension is installed and enabled, try running the php artisan reverb:start command again.

If you're still facing issues after following these steps, it might be helpful to check the documentation of Laravel Reverb or seek further assistance from the community or the maintainers of the package.
