Drupal 8-致命错误：无法实例化接口Drupal \\ Core \\ Cache \\ CacheBackendInterface

Question

当我尝试在drupal 8中安装admin_menu时收到此错误消息，请问其他人可以帮助我解决此错误..

Fatal error: Cannot instantiate interface Drupal\Core\Cache\CacheBackendInterface in C:\xampp5.6\htdocs\drupal-8\core\lib\Drupal\Component\DependencyInjection\Container.php on line 268

Answer 1

This is one of the known error in Drupal port and needs work.

variable_set('admin_menu_cache_client', FALSE);

variable_set is depreciated in Drupal8.
