Extension Install Error

[noeli-eshopguru]

Hi

I am trying to install this extension on our magento site.

Our magento version is 2.3.0 and PHP is 7.2.18

1. We tried the automatical install command but failed with many of errors.
   wget https://raw.githubusercontent.com/hps/heartland-magento2-module/master/HPS_Installer.php && php -f HPS_Installer.php | tee -a HPS_Heartland.log && sh HPS_Install.sh | tee -a HPS_Heartland.log

2. Then we tried manual install.

• git clone https://github.com/hps/heartland-magento2-module.git
  This command was successful and we got the repository for the extension.
• composer require hps/heartland-php
  This command is making too many errors. So we couldn't install the dependencies for the extension.
  The error messages are:

Using version ^2.12 for hps/heartland-php
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
