project uses the typescript style, and then customizes a component, but when called, did you register the component correctly? is reported. For recursive components, make sure to provide the "name" option.? Define the name of the component? But 
 < template lang="pug" > 
 div 
 < / template > 
 < script lang="ts" > 
 import {Component, Vue} from "vue-property-decorator"; 
 @ Component 
 export default class extends Vue {} 
 < / script > 
< style lang="less" scoped >
 < / style > 
 ask this name to write like this!
