error when install the package

[mohamedhussieen]

Problem 1

• lcobucci/jwt[4.1.0, ..., 4.2.x-dev] require ext-sodium * -> it is missing from your system. Install or enable PHP's sodium extension.
• kreait/laravel-firebase 4.1.0 requires kreait/firebase-php ^6.0 -> satisfiable by kreait/firebase-php[6.0.0, ..., 6.x-dev].
• kreait/firebase-php[6.0.0, ..., 6.x-dev] require lcobucci/jwt ^4.1 -> satisfiable by lcobucci/jwt[4.1.0, ..., 4.2.x-dev].
• Root composer.json requires kreait/laravel-firebase ^4.1 -> satisfiable by kreait/laravel-firebase[4.1.0].

To enable extensions, verify that they are enabled in your .ini files:

• C:\xampp\php\php.ini You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

any help please

As the error message describes, you've got to make sure the sodium extension is enabled in your installation. There have been XAMPP users experiencing similar problems.

Since this is not a problem directly related to this package, I'm sorry I can't provide further support.
