Cannot resolve module
跟着老师的代码敲得，但是出现错误：Cannot resolve module babel-runtime/core-js/json/stringify
store.js里的代码如下
const STORAGE_KEY='todos-vuejs'
export default {
fetch(){
return JSON.parse(window.localStorage.getItem(STORAGE_KEY)||'[]');
},
save(items){
window.localStorage.setItem(STORAGE_KEY,JSON.stringify(items))
}
}
