javascript - requirejs加载报错问题？-PHP中文网问答

1、使用requirejs写了个demo.html，第一次加载页面时能够正常显示，随后刷新页面就开始报错，虽然页面还是正常显示，但是我不理解为什么会这样。
2、我的另一个999.html文件（跟demo.html在同级目录下，但是页面内容比较多，其余和1中的html没有太大区别）一直报错，要么显示require is not define要么显示Script error for "jquery"或$ is not defined，请问这是为什么，应该怎么改？

以下是文件目录：

代码如下：

demo.html：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title></title>
        <script src="resource/require.js"></script>
        <script src="resource/main.js"></script>
    </head>
    <body>
        <script type="text/javascript">
            require(['jquery','weui'],function($){
                $('body').css('background','red');
                
            });
        </script>
    </body>
</html>

main.js：

require.config({
    baseUrl:'resource/app',
    paths:{
        'jquery':'../lib/jquery-3.2.0.min',
        'zepto':'../lib/zepto.min',
        'css':'../lib/css.min',
        'weui':'../lib/jquery-weui.min',
        'cookie':'../lib/jquery.cookie',
        'swiper':'../lib/swiper'
    }
});

报错信息：
