[Checkout.com] Cannot override final method Df\Payment\Method::acceptPayment() in vendor/magento2/checkout.com/Method.php

Hello, please help. During
bin/magento setup:di:compile
I get:
PHP Fatal error: Cannot override final method Df\Payment\Method::acceptPayment() in /var/www/mini/vendor/magento2/checkout.com/Method.php on line 21

I changed method to not final.
Then during
bin/magento setup:di:compile

I get:
Fatal error: Class ‘Df\Payment\ConfigProvider\StripeClone’ not found in /var/www/mini/vendor/magento2/checkout.com/ConfigProvider.php on line 3

I think that maybe sometimes with versions mage2pro and magento2 is bad?

Sincerely

You are wrong: there is no acceptPayment method defined in the \Dfe\CheckoutCom\Method class in the latest 1.1.18 release.
An usual reason of such errors is ignorance or violation of the official installation and upgrading instructions.

Thank you very much. When I run composer require magento2/checkout.com:* (with --prefer-source , after cleaning composer cache and so on), I always get version 1.1.10.
