Question

我已经设置了Bootstrap Navbar，但是当我尝试单击汉堡包时，我的控制台上出现此错误：

Uncaught TypeError: Cannot read property 'querySelectorAll' of null
at a.t._getParent (collapse.js:308)
at new a (collapse.js:88)
at HTMLDivElement.<anonymous> (collapse.js:351)
at Function.each (jquery.min.js:2)
at n.fn.init.each (jquery.min.js:2)
at n.fn.init.a._jQueryInterface (collapse.js:337)
at HTMLDivElement.<anonymous> (collapse.js:385)
at Function.each (jquery.min.js:2)
at n.fn.init.each (jquery.min.js:2)
at HTMLButtonElement.<anonymous> (collapse.js:381)

这是我的导航栏：

<nav id="header_navbar" class="navbar navbar-expand-md navbar-light bg-header">
<a href="http://localhost/wordpress" class="navbar-brand"><img class="navbar-img" src="http://localhost/wordpress/wp-content/themes/Avada/images/technisol_logo.png"></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation" data-parent="accordian-10">
    <span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent" data_parent="#header_navbar">
  <ul class="navbar-nav justify-content-end"><li class="nav-item">
      <a class="nav-link text-dark" href="http://localhost/wordpress/login">Connexion</a>
    </li>
    <li class="nav-item">
      <a class="nav-link text-dark" href="http://localhost/wordpress/register">Inscription</a>
    </li>
  </ul>
</div>

我尝试了许多在Internet上找到的解决方案，例如：https://github.com/twbs/bootstrap/issues/26891

或者这一个： Cannot read property 'querySelectorAll' of null bootstrap collapse

什么都没有改变。

有什么想法吗？
