I think the root has something to do with the way mixins are being imported and exported from index.js.

import mixins from './mixins/index

This should be fixed with #1594

A quick temp fix for this issue can be to explicitly import VueSelect instead of using the default import.

in case of the example the code would be

import { VueSelect as vSelect } from 'vue-select';

That worked 👍
