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

<div class="wxParse" :class="className" v-if="!loading">
  <block v-for="node of nodes" :key="node.index">
    <wxParseTemplate :node="node" />
  </block>
</div>
这里的:key需要修改下不然会导致页面卡的现象，我是改成了<block v-for="(node, index) of nodes" :key="index">
