composer install

      Problem 1
    - jeremy-dunn/php-fedex-api-wrapper is locked to version 5.0.1 and an update of this package was not requested.
    - jeremy-dunn/php-fedex-api-wrapper 5.0.1 requires ext-soap * -> it is missing from your system. Install or enable PHP's soap extension.

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.
