1、跟着老师敲视频，做项目的时候；不知道怎么回事? 分析报错

in ./src/components/NavHeader.vue?vue&type=script&lang=js&

"export 'default' (imported as 'mod') was not found in '-!../../node_modules/cache-loader/dist/cjs.js??ref--1-0!../../node_modules/vue-loader/lib/index.js??vue-loader-options!./NavHeader.vue?vue&type=script&lang=js&'

2 解析

in ./src/components/NavHeader.vue?   首先是这个页面发生的错误；找到这个页面找报错的位置

3

export 'default' (imported as 'mod') was not found in '-!../../node_modules/   发现  组件未注册

4、注册一下

export default {
  components: {
    NavBar,
  },
};

就好了
