首先引入ueditor自带的两个文件

<!-- 不通版本的ueditor，引入的文件路径也可能不一致。根据自己的路径修改 -->
<link rel="stylesheet" href="/assets/ueditor/third-party/SyntaxHighlighter/shCoreDefault.css" />
<script src="/assets/ueditor/third-party/SyntaxHighlighter/shCore.js"></script>

然后在script中调用高亮方法即可

<script>
    SyntaxHighlighter.all();
</script>
