Webpack构建错误，同时包括第三方模块 - 角度4

Question

我收到了webpack编译错误。我已经使用CLI安装了bootstrap模块并尝试编译。在构建应用程序时，它显示以下错误

我更新了angular-cli.json文件

"styles": [
        "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.min.js"
      ],
