未捕获的ReferenceError：jQuery没有定义
我在我的网站上实现了一些JavaScript，但我不断收到以下错误消息：
未捕获的ReferenceError：未定义jQuery
和
未捕获的SyntaxError：意外的标记<
这是我在header.php中使用的JavaScript：

jQuery需要成为您导入的第一个脚本。 您网页上的第一个脚本
<script type="text/javascript" src="/test/wp-content/themes/child/script/jquery.jcarousel.min.js"></script>
似乎是一个jQuery 插件 ，这可能会产生一个错误，因为jQuery尚未加载在页面上呢。
你需要把它放在wp_head（）之后; 因为加载你的jQuery，你需要先加载jQuery，然后加载你的js
在我的情况下，错误发生，因为我使用jquery的错误版本。
<script src="jquery-migrate-1.2.1.min.js"></script>
我把它改成：
<script src="jquery-1.11.3.min.js"></script>
首先，你似乎没有在头文件中包含jQuery本身，而只包含一堆插件。 至于“<”错误，不可能看到生成的HTML。
设置这个jquery min js
script src="jquery-1.10.1.min.js"
在wp-admin / admin-header.php中
