vue3 installation vue-grid-layout displays [Vue warn]: Invalid vnode type when creating vnode: undefined.

Problem description: After installation in vue3+ts+vite environment, [email protected][Vue warn]: Invalid vnode type when creating vnode: undefined is displayed.

problem solved:

1. Do not introduce it in the componentimport { GridLayout, GridItem } from "vue-grid-layout"
2. Use it directly in main.tsthe file as follows:

   import VueGridLayout from 'vue-grid-layout'
   // ...
   app.use(VueGridLayout)
