Memory exhausted and PHP Version mismatch errors. Not able to install image intervention laravel 5.5 package

I want to change color of my image. So I'm trying to use image/intervention of laravel. Followed their documentation: http://image.intervention.io/getting_started/installation https://packagist.org/packages/intervention/image

When i tried the following, i got an memory exhausted error:

1. composer require intervention/image

Error: PHP Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar://C:/ProgramData/ComposerSetup/bin/composer.phar/src/Composer/DependencyResolver/Solver.php on line 223

Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors. E:\xampp\htdocs\Myproject>php -r "echo ini_get('memory_limit').PHP_EOL;" 512M

So, i followed the below link and increased to memory_limit=-1 from memory_limit=512M https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors

Now, again tried this command composer require intervention/image. Now i got a different error:

Error: Your requirements could not be resolved to an installable set of packages.

Problem 1 - This package requires php ~7.2.0 but your PHP version (7.3.11) does not satisfy that requirement. Problem 2 - mpociot/vat-calculator dev-master requires ext-soap * -> the requested PHP extension soap is missing from your system. - mpociot/vat-calculator dev-master requires ext-soap * -> the requested PHP extension soap is missing from your system. - mpociot/vat-calculator dev-master requires ext-soap * -> the requested PHP extension soap is missing from your system. - Installation request for mpociot/vat-calculator dev-master -> satisfiable by mpociot/vat-calculator[dev-master].

To enable extensions, verify that they are enabled in your .ini files: - E:\xampp\php\php.ini You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

Why am i getting these errors? How can i install image/intervention package in my application? I'm using laravel 5.5 , PHP 7.3.11

As the error says, do i have to install 7.2.0 php version? Or is there any other solutions?
