In your code, you don’t need to create another instance of Vue. I can’t imagine a situation where you need to create a new Vue instance in a single file component. Uou can use components if you need to encapsulate some functionality
If you do need to do this, you can use the following code:
import Vue from 'vue'
new Vue({
...
})
please see vue’s official documentation and sample projects

Old question, but if someone needs it
If you have new Vue({}) in a js file and you load that js file before loading vuejs javascript file, you will get this error. This was the reason for my error.
Basically add /vue.min.js”> before you add other js files using vuejs
Hope it helps

I think You miss to add vue.js file, example:
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.18/vue.min.js"></script>
