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？
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：

手动声明依赖
以及 999.html 中加载 require.js 时不要 defer 和 async
