Twig debug不工作 && 使用twig不存储cache

settings.php

if (file_exists($app_root . '/' . $site_path . '/settings.local.php')) {
   include $app_root . '/' . $site_path . '/settings.local.php';
}

settings.local.php

ini_set('memory_limit', '2048M');
/**
 * Enable local development services.
 */
$settings['container_yamls'][] = DRUPAL_ROOT . '/sites/services.local.yml';

//twig 不存cache，方便debug，services.local.yml需要引入cache.backend.null
$settings['cache']['bins']['render'] = 'cache.backend.null';
$settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.null';

$settings['system.performance']['css']['preprocess'] = FALSE;
$settings['system.performance']['js']['preprocess'] = FALSE;
