net core中bootshrap下拉菜单无效

如下是css引用

<environment include="Development">
        <link href="~/lib/twitter-bootstrap/css/bootstrap.css" rel="stylesheet" />
        <link href="~/lib/font-awesome/css/font-awesome.css" rel="stylesheet" />
    </environment>
    <environment exclude="Development">
        <link rel="stylesheet"
              href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"
              integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T"
              crossorigin="anonymous"
              asp-fallback-href="~/lib/twitter-bootstrap/css/bootstrap.min.css"
              asp-fallback-test-class="sr-only"
              asp-fallback-test-property="position"
              asp-fallback-test-value="absolute"
              asp-suppress-fallback-integrity="true" />
        <link href="~/lib/font-awesome/css/font-awesome.min.css" rel="stylesheet" />
    </environment>

如下是js引用

<environment include="Development">
        <script src="~/lib/jquery/jquery.js"></script>
        <script src="~/lib/twitter-bootstrap/js/bootstrap.js"></script>
        <script src="~/lib/jquery-validate/jquery.validate.js"></script>
        <script src="~/lib/jquery-validate-unobtrusive/jquery.validate.unobtrusive.js"></script>
    </environment>
    <environment exclude="Development">
        <script src="~/lib/jquery/jquery.min.js"></script>
        <script src="~/lib/twitter-bootstrap/js/bootstrap.js"></script>
        <script src="~/lib/jquery-validate/jquery.validate.min.js"></script>
        <script src="~/lib/jquery-validate-unobtrusive/jquery.validate.unobtrusive.min.js"></script>
    </environment>

如下是下拉代码段

<li class="nav-item dropdown">
      <a href="#" class="nav-link dropdown-toggle" data-toggle="dropdown" id="navbarDropDownMenuLink"
            aria-haspopup="true" aria-expanded="false">
               管理
       </a>
       <div class="dropdown-menu" aria-labelledby="navbarDropDownMenuLink">
                <a class="dropdown-item" asp-controller="Admin" asp-action="ListUsers">用户列表</a>
                <a class="dropdown-item" asp-controller="Admin" asp-action="ListRoles">角色列表</a>
        </div>
 </li>

查了一些资料都是关于引用顺序不正确导致的，解决无效，请各位指教！3Q
