javascript - 导航栏在 Bootstrap 中不起作用 : 4. 0.0-beta.2

Question

我已经安装了最新版本的Bootstrap:

"@ng-bootstrap/ng-bootstrap": "^1.0.0-beta.5",
"bootstrap": "^4.0.0-beta.2",
"core-js": "^2.4.1",
"jquery": "^3.2.1",
"popper.js": "^1.12.9",

我实现了一个导航栏:

<nav class="navbar navbar-expand-md navbar-light bg-light" *ngIf="!isLogged">
  <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active" routerLinkActive="active current">
        <a class="nav-link" routerLink="/sign-up"><span class="">Sign Up</span></a>
      </li>
      <li class="nav-item active" routerLinkActive="active current">
        <a class="nav-link" routerLink="/login"><span class="">Login</span></a>
      </li>
    </ul>
  </div>
</nav>

移动尺寸时应转换为 button。实际上它确实如此，但是 button 不会对任何点击使用react。为什么？有没有人有任何线索？我没有向 angular.cli 添加任何脚本。

更新: project structure

  "dependencies": {
    "@angular/animations": "^4.0.0",
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",
    "@angular/core": "^4.0.0",
    "@angular/forms": "^4.0.0",
    "@angular/http": "^4.0.0",
    "@angular/platform-browser": "^4.0.0",
    "@angular/platform-browser-dynamic": "^4.0.0",
    "@angular/router": "^4.0.0",
    "@ng-bootstrap/ng-bootstrap": "^1.0.0-beta.5",
    "bootstrap": "^4.0.0-beta.2",
    "core-js": "^2.4.1",
    "jquery": "^3.2.1",
    "popper.js": "^1.12.9",
    "rxjs": "^5.4.1",
    "zone.js": "^0.8.14"
  },

这是你的 .angular-cli.json 中应该有的内容

"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"
  ],
"styles": [
    "styles.css",
    "../node_modules/bootstrap/dist/css/bootstrap.css"
  ]
