当我将 Jquery 和 popper.js 集成到 angular 时，它不起作用

Question

I want to integrate jquery and popper.js in my angular project I installed both and add to packages.json as well as in angular.json but it doesn't work

packages.json :

    "@angular/animations": "~10.0.6",
    "@angular/common": "~10.0.6",
    "@angular/compiler": "~10.0.6",

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

Answer 1

First did you do it manually or by npm ? Second did you restart the server after installing ?

Answer 2

Finally I don't see where the problem is so I add the scripts in index.html now it works

      <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
