无法将.js文件加载到角4应用程序中

Question

我试图在我的角4应用程序(template - https://startbootstrap.com/template-overviews/agency/)中使用预先设计的引导模板。成功加载css样式。但是，当加载所需的.js文件时，它会发出以下警告。另外，.js文件应该提供的效果也不起作用。如何正确加载这些样式和.js文件？

角-cli.json

"scripts": [
    "../node_modules/jquery/dist/jquery.min.js",
    "assets/vendor/bootstrap/js/bootstrap.bundle.min.js",
    "assets/vendor/jquery-easing/jquery.easing.min.js",
    "assets/js/jqBootstrapValidation.js",
    "assets/js/contact_me.js",
    "assets/js/agency.min.js",
    "assets/js/agency.js"
  ],

在styles.css中

@import "~bootstrap/dist/css/bootstrap.min.css";
@import "~font-awesome/css/font-awesome.css";

在index.html中

确保bootstrap.bundle.min.js存在于供应商/目录中。我想您应该从node_modules/目录导入它。

"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/bootstrap/js/bootstrap.bundle.min.js",
"../node_modules/jquery-easing/jquery.easing.min.js",
...
]
