Angular 6 和 Bootstrap 4 可折叠 div 不起作用

Question

bootstrap4 提供 Accordion 控件https://getbootstrap.com/docs/4.0/components/collapse/#accordion-example

当我尝试将它与我的 angular 6 应用程序一起使用时，它不会崩溃。浏览器中没有错误，但它不起作用。对此有什么想法吗？

<div class="accordion" id="accordionExample">
  <div class="card">
    <div class="card-header" id="headingOne">
      <h5 class="mb-0">
        <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </button>
      </h5>
    </div>

    <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
      <div class="card-body">

  </div>
</div> 

这是实时代码示例 https://stackblitz.com/github/Rugved/ng6bt4Demo/jquery 包含在 angular.json 文件中

"styles": [
  "src/styles.css",
  "node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
  "node_modules/jquery/dist/jquery.min.js",    
  "node_modules/popper.js/dist/umd/popper.min.js",
  "node_modules/bootstrap/dist/js/bootstrap.js"                        
]

你的代码对我来说工作得很好。

请找到以下配置

package.json

{
"bootstrap": "^4.1.3",
"popper.js": "^1.14.3",
"jquery": "3.3.1"
}

angular.json

"styles": [
              "src/styles.scss",
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
            ],
            "scripts": [
              "node_modules/jquery/dist/jquery.min.js",
              "node_modules/bootstrap/dist/js/bootstrap.min.js"
            ]
