"Failed to mount component” error on Laravel 5.3.10 + Vue.js 2.0.1

I have been working on Laravel + Vue.js. I would like to develop Vue components onto Laravel Blade template, but when I tried doing that, the following error occured, and it doesn’t work well.
* For the purpose of checking, I have just written only a minimal code of Vue components.

I tried various things in reference to the following articles.

The problem which is occuring and the error message

[Vue warn]: Failed to mount component: template or render function not defined. (found in anonymous component - use the "name" option for better debugging messages.)
