Bootstrap4依赖关系PopperJs在Angular上抛出错误

Question

我刚刚创建了一个全新的angular-cli项目
并运行npm install bootstrap@4.0.0-beta jquery popper.js --save
并更改了.angular-cli.json的相关部分,如下所示

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

但是接收到以下错误

10:2287 Uncaught SyntaxError: Unexpected token export
    at eval (<anonymous>)
    at webpackJsonp.../../../../script-loader/addScript.js.module.exports (addScript.js:9)
    at Object.../../../../script-loader/index.js!../../../../popper.js/dist/popper.js (popper.js?4b43:1)
    at __webpack_require__ (bootstrap 4403042439558687cdd6:54)

    at webpackJsonpCallback (bootstrap 4403042439558687cdd6:25)
    at scripts.bundle.js:1

任何想法如何解决它？

提前致谢...

查看https://getbootstrap.com/docs/4.2/getting-started/introduction/#js上的文档,您可以看到它们导入以下内容:

<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>

注意命名:jquery.苗条 .min.js,umd /popper.min.js!

因此,我用我的下面.angular-cli.json:

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

之后它似乎现在起作用了.

我有同样的问题.我的解决方案是不导入dist文件夹(./node_modules/popper.js/dist/popper.js),而是导入umd文件夹(./node_modules/popper.js/dist/ umd /popper.js).如果你得到js文件的迷你或普通版本无关紧要.
