bootstrap-4 - 为什么即使安装依赖项并导入后，bootstrap 4 dropdowm和切换按钮也无法正常工作？(why does bootstrap 4 dropdowm and toggle button does not work even after installing dependencies and importing it?)

Question

This is what i have tried!

(这就是我尝试过的！)

https://navbarex.stackblitz.io

(https://navbarex.stackblitz.io)

i have installed bootstrap, jquery and popper.js

(我已经安装了bootstrap，jquery和popper.js)

and i have imported that in angular.json file

(我已经将它导入了angular.json文件中)

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

        ]

same thing i have tried in my local machine its working fine but why not here in StackBlitz?

(我在我的本地计算机上尝试过的同样的东西，但工作正常，但为什么在StackBlitz中却没有呢？)
