Drupal升级后缺少Drupal模块

我对Drupal很陌生。我有一个运行在Red Hat Linux上的网站。我按照以下步骤升级到8.9.9。简言之，我已经做到了

Select all the files in the top-level directory (also hidden files starting with a dot) as well as
 the 'core' and 'vendor' directories, and delete them. Be sure not to delete the 'modules', 
'profiles', 'sites', and 'themes' directories.

现在，当我按照所有步骤运行update.php时

Symfony\Component\DependencyInjection\Exception\LogicException: Service
 'dzango.twig.truncate_extension' for consumer 'twig' does not implement 
Twig\Extension\ExtensionInterface. in Drupal\Core\DependencyInjection\Compiler\TaggedHandlersPass->processServiceCollectorPass()
 (line 164 of /var/www/html/add-main/core/lib/Drupal/Core/DependencyInjection/Compiler/TaggedHandlersPass.php).
    
    Drupal\Core\DependencyInjection\Compiler\TaggedHandlersPass->processServiceCollectorPass(Array, 'twig', Object) (Line: 97)
    Drupal\Core\DependencyInjection\Compiler\TaggedHandlersPass->process(Object) (Line: 140)
    Symfony\Component\DependencyInjection\Compiler\Compiler->compile(Object) (Line: 789)
    Symfony\Component\DependencyInjection\ContainerBuilder->compile() (Line: 1335)
    Drupal\Core\DrupalKernel->compileContainer() (Line: 916)
    Drupal\Core\DrupalKernel->initializeContainer() (Line: 477)
    Drupal\Core\DrupalKernel->boot() (Line: 707)
    Drupal\Core\DrupalKernel->handle(Object) (Line: 19)

我发现升级后这些东西不见了

升级后是否需要运行一些composer命令？

我认为升级文档遗漏了非常重要的部分。从composer.json引入更改后，永远不要忘记运行composer安装/update/require。我没有手动将我的所有更改从my composer.json转换为新的，而是用我所需的包运行了

composer require mypackage

，并且运行正常。

尝试使用此代码更新所有包

composer update -vvv
