无法将Bootstrap 4，jQuery和PopperJS库添加到.angular-cli.json

Question

Currently i'm trying to implement Bootstrap 4 navbar element on my Angular 5 project, and it needs three JS libraries, Bootstrap 4, jQuery, and PopperJS. 目前，我正在尝试在Angular 5项目上实现Bootstrap 4 navbar元素，它需要三个JS库，即Bootstrap 4，jQuery和PopperJS。

It works flawlessly (ie NO ERROR occurred) when I add following to src/index.html 当我在src/index.html添加以下内容时，它可以完美地工作（即没有错误发生）

<head>
...
...
...
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script>
</head>

However, I wanted to do an experiment by adding those three JS libraries to the .angular-cli.json (instead of using CDN on src/index.html ), so I did following: 但是，我想做一个实验，将这三个JS库添加到.angular-cli.json （而不是在src/index.html上使用CDN），所以我做了以下工作：

On .angular-cli.json , i add: 在.angular-cli.json ，我添加：

"scripts": [
        "../node_modules/jquery/dist/jquery.slim.min.js",
        "../node_modules/popper.js/dist/popper.js",
        "../node_modules/bootstrap/dist/js/bootstrap.min.js"        
      ],

Note: before adding those three scripts to .angular-cli.json I already installed Bootstrap 4, jQuery and PopperJS packages using npm . 注意：在将这三个脚本添加到.angular-cli.json我已经使用npm安装了Bootstrap 4，jQuery和PopperJS软件包。

When running it, there is an Error on console (Chrome Dev Tool) 运行它时，控制台上出现错误（Chrome开发工具）

Uncaught SyntaxError: Unexpected token export         scripts.bundle.js:2302

When clicking on the error message it brought to this line 当单击错误消息时，它显示到此行

export default Popper;

I'm kinda confused on what's happening and what's the real cause of the problem? 我对正在发生的事情以及问题的真正原因是什么感到困惑？ How to fix this error? 如何解决这个错误？

Answer 1

npm install --save bootstrap jquery popper.js

angular-cli.json: angular-cli.json：

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

Now u can launch your app 现在您可以启动您的应用了
