Navbar無法在引導程序中運行：4.0.0-beta.2

Question

我已經安裝了最新版本的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",

我實現了一個navbar ：

<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>

談到手機尺寸時，應將其轉換為button 。 確實可以，但是該button不會對任何點擊做出反應。 為什么？ 有人有任何線索嗎？ 我沒有向angular.cli添加任何腳本。

更新： 項目結構

  "dependencies": {
    "@angular/animations": "^4.0.0",
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",
    "@angular/core": "^4.0.0",

    "popper.js": "^1.12.9",
    "rxjs": "^5.4.1",
    "zone.js": "^0.8.14"
  },

Answer 1

這是您在.angular-cli.json中應該包含的內容

"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"
  ]
