我使用以下命令安装了Django：conda create --name myproject django
我所做的每项检查（环境，django，版本等）似乎都还可以，我不知道问题出在哪里。

该问题的解决方法是什么？
答案 0 :(得分：0)
我找到了答案。
看来$("#loop").on('click',function(){
kid= $("#some123").children();
kid.each(function(index, element){
console.log($(element).html());
});
})
$("#loop2").on('click',function(){
kid= $("#some123").find('li');
kid.each(function(index, element){
console.log($(element).html());
});
})软件包管理器无法在我的Windows 10安装中正常工作。
解决方案是使用<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ol id='some123'>Items
<li draggable='true'>Item 1</li>
<li draggable='true'>Item 2</li>
<li draggable='true'>Item 3</li>
<li draggable='true'>Item 4</li>
</ol>
<div id='loop'>Loop1</div>
<div id='loop2'>Loop2</div>软件包管理器进行安装。

conda希望没有人会花那么多时间来找到一种非常简单的解决方案。 哇！
