Question:

Failed to resolve component: van-cell-group 
  at <Home onVnodeUnmounted=fn<onVnodeUnmounted> ref=Ref< undefined > key=0 >

Reason: the van cell group component is not imported

Solution:

You can import it in the ‘main. JS’ file and then use it on the page

The details are as follows:

import {
	createApp
} from 'vue'
import {
	CellGroup
} from 'vant'
createApp(App).use(CellGroup)
