【问题描述】：
我一直在尝试使用 Bootstrap 4.1.1 和 Angular 6 处理带有折叠菜单和下拉链接的导航栏，但不知何故，导航栏根本不起作用。我可以正确看到元素，但它们没有按预期运行。
我使用 'ng install bootstrap --save' 和 Bootstrap 依赖项通过 Angular CLI 安装了 Bootstrap：'ng install jquery --save' 和 'ng install popper.js --save'
我还在 package.json 和 angular.json 中包含了 Bootstrap、jquery 和 popper.js
package.json:
"dependencies": {
"@angular/animations": "^6.0.0",

}
angular.json:

"src/styles.css"
],
"scripts": [
"./node_modules/jquery/dist/jquery.min.js",
"./node_modules/popper.js/dist/popper.min.js",
"./node_modules/bootstrap/dist/js/bootstrap.min.js"
]
html:
<nav class="navbar navbar-expand-md navbar-light bg-light">
<a href="#" class="navbar-brand">RecipeBook</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsing-nav-bar" aria-controls="collapsing-nav-bar"
aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="collapsing-nav-bar">
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a href="#" class="nav-link">Recipes</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Shopping list</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item dropdown">
<a href="#" class="nav-link dropdown-toggle" id="dropdownMenu" data-toggle="dropdown"
aria-haspopup="true" aria-expanded="false">
Manage
</a>
<div class="dropdown-menu" aria-labelledby="dropdownMenu">
<a href="#" class="dropdown-item">Save</a>
<a href="#" class="dropdown-item">Fetch</a>
</div>
</li>
</ul>
</div>
</nav>
我更喜欢使用 Bootstrap 原生库，我宁愿不使用 ng-bootstrap 也不喜欢在 head-tag 中包含 CDN 之类的技巧。
我在这里做错了吗？任何有关如何解决此问题的建议将不胜感激。

要包含 bootstrap，您应该在您的 styles.css 文件中包含/导入 bootstrap css 文件，而不是 angular.json 中的
styles数组属性
