drupal - 不完整的库定义 drupal 8

Question

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 的片段。我在css文件夹和libraries中的css与路由yml文件同级。

        $element = array(

      '#attached' => array(
        'library' => array(

测试模块.libraries.yml

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

如果您的库是在您的模块/扩展中定义的，它应该为每个库条目包含以下所有必填字段:

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

您可以用您的 js、css 和 drupalSettings 替换大括号，如下所示:

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。
