【问题描述】：

您好，我收到以下错误。这段代码有什么问题？我正在尝试添加CSS。还在学习drupal 8。我想知道是什么问题。

这是我添加 css 的 sn-p。我的css文件夹和库中的css与路由yml文件处于同一级别。

这是我添加 css 的 sn-p。我的css文件夹和库中的css与路由yml文件处于同一级别。

        $element = array(
      '#markup' => '<p><b>Saying Hello World in Drupal 8 is cool!</b></p>' . $content,
      '#attached' => array(
        'library' => array(
          'test_module/test-module',
        ),
      ),
    );

test_module.libraries.yml

test_module_settings:
      path: '/hello/test'
      defaults:
        _controller: '\Drupal\test_module\Controller\TestModuleController::myCallbackMethod'
        _title: 'Hello World'
      requirements:
        _permission: 'view hello world'

【问题讨论】：

请提供您将 css 添加到模块的文件
@greg606 添加了 sn-p
和 *.libraries.yml 文件的内容？
@greg606 添加了libraries.yml

标签： drupal drupal-8

【解决方案1】：

如果您的库是在您的模块/扩展中定义的，则每个库条目都应包含以下所有必填字段：

my-library-entry:
  js: {}
  css: {}
  drupalSettings: {}

您可以像这样用js、css 和drupalSettings 替换花括号：

my-library-entry:
  js:
    misc/ajax.js: {}
  css:
    theme:
      css/cuddly-slider.css: {}
  drupalSettings:
    myDrupalSetting: null

我不知道为什么需要 drupalSettings 条目，但似乎是这样。

【解决方案2】：

*.libraries.yml 的内容似乎不正确。这是应该进入 routing.yml 的内容。

libraries.yml 应该看起来不同： https://www.drupal.org/developing/api/8/assets

cuddly-slider:
  version: 1.x
  css:
    theme:
      css/cuddly-slider.css: {}
  js:
    js/cuddly-slider.js: {}
