導航欄引導渲染問題

我最近想做一個應用程序使用的是Node.js，試圖呈現一些HTML與引導框架，但問題是，導航欄顯示那樣：導航欄引導渲染問題

我複製/粘貼完全文檔的演示代碼中發現有：https://v4-alpha.getbootstrap.com/components/navbar/

所以，我不知道什麼是這裏的問題：/

編輯1：顯然，這是同樣的問題，在本地，無需服務器或anythi納克

確定我重新定義了CDN用於引導和C/P的與導航欄演示最新版本的示例上引導V4的DOC實測值（最新，而不是所述αV *）現在看起來很好。

那麼，問題是與那些引導鏈接。

引導CDN

當你只需要包括引導的編譯CSS或者JS，你可以使用引導CDN。

CSS只

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous">

JS，波普爾和jQuery

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script> 

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script> 

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js" integrity="sha384-h0AbiXch4ZDo7tp9hKZ4TsHbi047NrKGLO3SEJAg45jXxnGIfYzk4Si90RDIqNm1" crossorigin="anonymous"></script>

我希望這將有助於。有一個偉大的旅程，網絡開發者的世界！
