Primefaces滑块不出现

Question

我正在尝试添加一个primefaces滑块元素，但是它根本不会出现/显示/显示。就像，我把它放在<h:body>内的<h:head>（<h:form>也存在）中：

<h:inputHidden id="R"/> <p:slider for="R" minValue="2" maxValue="5" step="1" id="Rslider"/>

在我放置的位置html中没有任何内容（几乎没有标签）。

控制台记录以下内容：

jquery-3.3.1.min.js:2 jQuery.Deferred exception: this.jq.slider is not a function TypeError: this.jq.slider is not a function

和

Uncaught TypeError: this.jq.slider is not a function

试图下载不同的版本和主题，但没有结果。

<p:inputText>

和<p:spinner>可以正常工作。
