推荐答案

这是由于模板组件的弃用，请参阅 https://symfony.com/blog/new-in-symfony-4-3-deprecated-the-template-component-integration

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

解决方案:

从 composer.json

"symfony/template"

从 framework.yaml 中删除:

templating:
    engines:
        - twig

运行 composer 更新

这应该会删除所有弃用警告.

This should remove all the deprecation warnings.

如果您收到此错误

无法自动装配服务...":方法__construct()"的参数$templating"引用了接口SymfonyBundleFrameworkBundleTemplatingEngineInterface"，但不存在此类服务.您是否创建了实现此接口的类?

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?

...您仍在某些服务中使用旧模板.
解决方法:将依赖从SymfonyBundleFrameworkBundleTemplatingEngineInterface改为TwigEnvironment:

... 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;
}
