main.js 코드를 다음과 같이 바꿔보세요.

import Vue from 'vue';
import TicTacToe from './TicTacToe';

new Vue(TicTacToe).$mount('#root');

똑같은 에러라서... 제가 뭔가 잘못하고 있는건가요?

위에는 선생님 깃허브에서 다운받아서 작동해봤구요... 밑에는

this.$root.$data가 들어오지를 않습니다...

{__ob__: Observer}
__ob__: Observer
dep: Dep {id: 3, subs: Array(0)}
value: {__ob__: Observer}
vmCount: 1
__proto__: Object
__proto__: Object

TdComponent.vue?c5a7:15 {__ob__: Observer}
parant: (...)
__ob__: Observer {value: {…}, dep: Dep, vmCount: 1}
get parant: ƒ reactiveGetter()
set parant: ƒ reactiveSetter(newVal)
__proto__: Object
도저히 못찾겠어요.. 건너뛰어야 할까요?

1 of undefined라는데 x[1]이 있다면 x가 undefined인 것입니다. 왜 x가 undefined인지 console.log로 추적해보세요.
