Question

我已经创建了聊天模块模板。昨天工作正常，但是今天npm模块中存在一些问题，因此我运行了命令npm audit fix --force，该命令完成后，我的聊天模板或任何VUE模板停止工作意味着它没有显示。这是我模板的代码。

这就是我在刀片模板中调用模板的方式。

@section('content')
<div class="container-fluid">

 @endsection

我的laravel-echo-server，redis服务器或npm中都没有错误，但是仍然没有出现。我已经尝试了一些解决方案，但是都没有用。

任何有关此问题的帮助将不胜感激。预先谢谢你。
