drupal 8启用树枝调试无法正常工作？

Question

我正在设法解决这个问题：我不知道为什么调试调试不起作用：
Drupal版本8.2.6

Folder structure

。

Folder permissions

Settings.php

$settings['hash_salt'] = 'DEVELOPMENT_SALT';
$settings['update_free_access'] = FALSE;
$settings['file_public_base_url'] = 'http://localhost/files';
$settings['file_public_path'] = 'sites/default/files';
$settings['file_private_path'] = 'sites/default/private';
$settings['file_scan_ignore_directories'] = [
  'node_modules',
  'bower_components',
];
if (file_exists(__DIR__ . '/../development/settings.development.php'))     {
  include __DIR__ . '/../development/settings.development.php';
}

/../development/settings.development.php

assert_options(ASSERT_ACTIVE, TRUE);
\Drupal\Component\Assertion\Handle::register();

/**
 * Enable local development services.
 */
$settings['container_yamls'][] = __DIR__ . '/development.services.yml';

$databases['default']['default'] = array(
  'database' => 'dbname',
  'username' => 'dbusername',
  'password' => 'pw',
  'prefix' => '',
  'host' => '127.0.0.1',
  'port' => '3306',
  'namespace' => 'Drupal\\Core\\Database\\Driver\\mysql',
  'driver' => 'mysql',
);

$settings['hash_salt'] = 'DEVELOPMENT';

$config['system.logging']['error_level'] = 'verbose';
$config['system.performance']['css']['preprocess'] = FALSE;
$config['system.performance']['js']['preprocess'] = FALSE;
$settings['cache']['bins']['render'] = 'cache.backend.null';
$settings['cache']['bins']['dynamic_page_cache'] =     'cache.backend.null';
$settings['extension_discovery_scan_tests'] = TRUE;
$settings['rebuild_access'] = TRUE;
$settings['skip_permissions_hardening'] = TRUE;

development.services.yml

parameters:
  http.response.debug_cacheability_headers: true
  twig.config:
    debug: true
    auto_reload: true
    cache: false
services:
  cache.backend.null:
    class: Drupal\Core\Cache\NullBackendFactory

我检查/完成的事情：

• 检查是否所有这些文件都已加载->它们已加载。
  
• 检查了development.services.yml的缩进->检出。
  
• 清除所有不同的缓存，重建它们，...
  

如果更改模板，则它会更改，但不会进行细枝调试。

奇怪的是：Drupal不使用站点/默认/文件和站点/默认/私有。

我建议不要将development.services.yml文件重命名为services.yml，因为这会导致所有开发代码/配置/设置在生产环境中应用和运行。相反，请按设计使用开发文件。

这是我们的标准设置：

/sites/default/settings.php（在版本控制中）在最底部包含以下内容，以便我们仅在应有的实例上加载开发内容。例如不生产：

/**
 * Load local development override configuration, if available.
 *
 * Keep this code block at the end of this file to take full effect.
 */
if (file_exists(__DIR__ . '/settings.local.php')) {
  include __DIR__ . '/settings.local.php';
}

我们的/sites/default/settings.local.php（不在版本控制中）至少包含以下内容：

<?php

/**
 * Disable css and js preprocessing.
 */
$config['system.performance']['css']['preprocess'] = FALSE;
$config['system.performance']['js']['preprocess'] = FALSE;

/**
 * Disable Render Cache and Dynamic Page Cache.
 */
$settings['cache']['bins']['render'] = 'cache.backend.null';
$settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.null';

/**
 * Enable local development services.
 */
$settings['container_yamls'][] = DRUPAL_ROOT . '/sites/development.services.yml';

/**
 * Enable access to rebuild.php.
 */
$settings['rebuild_access'] = TRUE;

最后，我们的/sites/development.services.yml（在版本控制中）文件包含以下内容：

# Local development services.
#
# To activate this feature, follow the instructions at the top of the
# 'example.settings.local.php' file, which sits next to this file.
parameters:
  http.response.debug_cacheability_headers: true
  twig.config:
    debug: true
    auto_reload: true
    cache: false
services:
  cache.backend.null:
    class: Drupal\Core\Cache\NullBackendFactory

这对我们来说真的很好。

要启用 Twig 调试，您需要复制（“default.services.yml”）并将其重命名为“services.yml”。并将“debug: false”设置为 true。

例如：services.yml

parameters:
  session.storage.options:
    # Default ini options for sessions.
    #
    # Some distributions of Linux (most notably Debian) ship their PHP
    # installations with garbage collection (gc) disabled. Since Drupal depends
    # on PHP's garbage collection for clearing sessions, ensure that garbage
    # collection occurs by using the most common settings.
    # @default 1
    gc_probability: 1
    # @default 100
    gc_divisor: 100
    #
    # Set session lifetime (in seconds), i.e. the time from the user's last
    # visit to the active session may be deleted by the session garbage
    # collector. When a session is deleted, authenticated users are logged out,
    # and the contents of the user's $_SESSION variable is discarded.
    # @default 200000
    gc_maxlifetime: 200000
    #
    # Set session cookie lifetime (in seconds), i.e. the time from the session
    # is created to the cookie expires, i.e. when the browser is expected to
    # discard the cookie. The value 0 means "until the browser is closed".
    # @default 2000000
    cookie_lifetime: 2000000
    #
    # Drupal automatically generates a unique session cookie name based on the
    # full domain name used to access the site. This mechanism is sufficient
    # for most use-cases, including multi-site deployments. However, if it is
    # desired that a session can be reused across different subdomains, the
    # cookie domain needs to be set to the shared base domain. Doing so assures
    # that users remain logged in as they cross between various subdomains.
    # To maximize compatibility and normalize the behavior across user agents,
    # the cookie domain should start with a dot.
    #
    # @default none
    # cookie_domain: '.example.com'
    #
  twig.config:
    # Twig debugging:
    #
    # When debugging is enabled:
    # - The markup of each Twig template is surrounded by HTML comments that
    #   contain theming information, such as template file name suggestions.
    # - Note that this debugging markup will cause automated tests that directly
    #   check rendered HTML to fail. When running automated tests, 'debug'
    #   should be set to FALSE.
    # - The dump() function can be used in Twig templates to output information
    #   about template variables.
    # - Twig templates are automatically recompiled whenever the source code
    #   changes (see auto_reload below).
    #
    # For more information about debugging Twig templates, see
    # https://www.drupal.org/node/1906392.
    #
    # Not recommended in production environments
    # @default false
    debug: true
    # Twig auto-reload:
    #
    # Automatically recompile Twig templates whenever the source code changes.
    # If you don't provide a value for auto_reload, it will be determined
    # based on the value of debug.
    #
    # Not recommended in production environments
    # @default null
    auto_reload: null
    # Twig cache:
    #
    # By default, Twig templates will be compiled and stored in the filesystem
    # to increase performance. Disabling the Twig cache will recompile the
    # templates from source each time they are used. In most cases the
    # auto_reload setting above should be enabled rather than disabling the
    # Twig cache.
    #
    # Not recommended in production environments
    # @default true
    cache: true
  renderer.config:
    # Renderer required cache contexts:
    #
    # The Renderer will automatically associate these cache contexts with every
    # render array, hence varying every render array by these cache contexts.
    #
    # @default ['languages:language_interface', 'theme', 'user.permissions']
    required_cache_contexts: ['languages:language_interface', 'theme', 'user.permissions']
    # Renderer automatic placeholdering conditions:
    #
    # Drupal allows portions of the page to be automatically deferred when
    # rendering to improve cache performance. That is especially helpful for
    # cache contexts that vary widely, such as the active user. On some sites
    # those may be different, however, such as sites with only a handful of
    # users. If you know what the high-cardinality cache contexts are for your
    # site, specify those here. If you're not sure, the defaults are fairly safe
    # in general.
    #
    # For more information about rendering optimizations see
    # https://www.drupal.org/developing/api/8/render/arrays/cacheability#optimizing
    auto_placeholder_conditions:
      # Max-age at or below which caching is not considered worthwhile.
      #
      # Disable by setting to -1.
      #
      # @default 0
      max-age: 0
      # Cache contexts with a high cardinality.
      #
      # Disable by setting to [].
      #
      # @default ['session', 'user']
      contexts: ['session', 'user']
      # Tags with a high invalidation frequency.
      #
      # Disable by setting to [].
      #
      # @default []
      tags: []
  # Cacheability debugging:
  #
  # Responses with cacheability metadata (CacheableResponseInterface instances)
  # get X-Drupal-Cache-Tags and X-Drupal-Cache-Contexts headers.
