日志：

[Vue warn]: Unknown custom element: <nuxt> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

设置：

1. 将其下载为zip文件，将其解压缩到某个位置，然后在 终奌站。 （CodeSandbox有时会出现故障）

3. 先将CD依次复制到express和yarn
4. 运行yarn build && yarn start
5. 转到localhost:3000

我做错了什么？
