Bootstrap 4.1.1 Navbar无法与Angular 6一起使用 [英] Bootstrap 4.1.1 Navbar not working with Angular 6

问题描述

我一直在尝试使用Bootstrap 4.1.1和Angular 6在带有折叠菜单和下拉链接的Navbar上工作，但是Navbar根本无法正常工作。我可以正确看到元素，但它们无法正常运行。

I have been trying to work on Navbar with collapse menu and dropdown link using Bootstrap 4.1.1 and Angular 6 but somehow Navbar is not working at all. I can see elements correctly but they don't function as intended.

我通过Angular CLI使用ng install bootstrap --save和Bootstrap依赖项安装了Bootstrap： install jquery --save'和'ng install popper.js --save'

I installed Bootstrap via Angular CLI using 'ng install bootstrap --save' and Bootstrap dependencies: 'ng install jquery --save' and 'ng install popper.js --save'

我还在package.json和angular.json中包含了Bootstrap，jquery和popper.js

I also included Bootstrap, jquery and popper.js in package.json and angular.json

package.json：

}

angular.json：

angular.json:

        "styles": [
          "./node_modules/bootstrap/dist/css/bootstrap.min.css",
          "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本机库，而宁愿不使用ng-bootstrap也不喜欢将CDN包含在头部标签。

I prefer using Bootstrap native library and I rather not use ng-bootstrap nor hacks like including CDNs in head-tag.

我在这里做错了吗？

推荐答案

只需在脚本中添加 umd 指令popper

just add umd directries popper in script.

 "./node_modules/popper.js/dist/umd/popper.min.js",
