Answer
This is due to the deprecation of the templating component, see https://symfony.com/blog/new-in-symfony-4-3-deprecated-the-templating-component-integration
Solution:
- Remove
"symfony/templating"fromcomposer.json - Remove this from
framework.yaml:templating: engines: - twig - Run
composer update
This should remove all the deprecation warnings.
If you’re getting this error
Cannot autowire service “…”: argument “$templating” of method “__construct()” references interface “SymfonyBundleFrameworkBundleTemplatingEngineInterface” but no such service exists. Did you create a class that implements this interface?
… you’re still using the old templating in some service.
Solution: Change the dependency from SymfonyBundleFrameworkBundleTemplatingEngineInterface to TwigEnvironment:
use TwigEnvironment;
private $twig;
public function __construct(Environment $twig)
{
$this->twig = $twig;
}
