First of all thank you for your quick response. I have Install extension from github which you provide me in you response. When i have install this module and run setup upgrade command it. It installed successfully. After Installation i have try to visit my checkout cart and show me error :
Fatal error: Uncaught Error: Cannot instantiate abstract class Df\StripeClone\ConfigProvider in magento_root/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:73 Stack trace: #0 magento_root/vendor/magento/framework/ObjectManager/ObjectManager.php(71): Magento\Framework\ObjectManager\Factory\Dynamic\Developer->create(‘Dfe\CheckoutCom…’) #1 magento_root/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(163): Magento\Framework\ObjectManager\ObjectManager->get(‘Dfe\CheckoutCom…’) #2 magento_root/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(139): Magento\Framework\ObjectManager\Factory\AbstractFactory->parseArray(Array) #3 magento_root/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php(53): Magento\Framework\ObjectManager\Factory\AbstractFactory->resolveArgument(Array, NULL, NULL, ‘configProviders’, ‘Magento\Checkou…’) #4 magento_root/vendor/magento/framework/ObjectManage in magento_root/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php on line 73
