DI compile giving error in Weprovide pdf module

[ram10rajtechM]

Hi Team,

I've integrated the module working fine.
While running the di:compile i'm getting some error.

Please check and let me know.

Error:

14% 1 sec 52.0 MiBPHP Fatal error: Declaration of WeProvide\Dompdf\Controller\Result\Dompdf::render(WeProvide\Dompdf\Controller\Result\HttpResponseInterface $response) must be compatible with Magento\Framework\Controller\AbstractResult::render(Magento\Framework\App\ResponseInterface $response) in /var/www/html/tempm/vendor/weprovide/magento2-module-dompdf/Controller/Result/Dompdf.php on line 116

This occurs when not using Magento 2.2 after this commit: a4b0e92

You can fix it by going to Line 89 in Dompdf.php and changing it to:

protected function render(ResponseInterface $response)

@performadigital I changed line 89 as you mentioned in your last reply, but I got this error while running di:compile

[RuntimeException]
Class Dompdf\Dompdf does not exist

[performadigital]

@msliman It sounds like you haven't run the composer install which requires the Dompdf library.

Using composer run:

composer require dompdf/dompdf

Then run the upgrade and compile commands.
