    这是因为微信很早以前就改过 wxml 获取 wx:for 变量的规则，比如以下代码

    // js
const list = [
  { id: '111', text: '111' },
  { id: '222', text: '222' }
 ]
 
// wxml

// bad
<block wx:for="{{ list }}" wx:key="{{ item.id }}">
  
</block>

// foo
// wx:key 如果想设置为 item.id 则不能使用双花括号方式，直接使用字符串加属性名即可
<block wx:for="{{ list }}" wx:key="id">
  
</block>

    wx:key="{{index}}" does not look like a valid key name (did you mean wx:key="index" ?)

    应该是key的问题: 试试wx:key="{{item.id}" 或者 wx:key="{{*this}}"

    这个看着不对吧<label wx:for="{{sex}}" wx:for-item="item" wx:key="{{item.id}}">

    试试改成<label wx:for="{{sex}}" wx:for="你的数据" wx:key="{{item.id}}">

    wx:key是得item里面的某一个属性名字，不能是动态的，

    比如遍历的数组是

    list=[{id:"1",name:"小红"},{id:"2",name:"小明"}]

    那么wx:key="id"或者wx:key="name"

    试试修改如下

    <label wx:for="{{sex}}" wx:for-item="item" wx:key="{{item.id}}">  改为 <label wx:for="{{sex}}" wx:for-item="item" wx:key="{{id}}">
