VueToast breaks project?

Question

Vue.js

Installed, plugged in and plugged in.

import VueToast from 'vue-toast-notification';
import 'vue-toast-notification/dist/theme-sugar.css';

Vue.use(VueToast)

this.$toast.open({
    message: 'Something went wrong!',
    type: 'error',
    // all of other options may go here
});

And as a result in the console I got:

Uncaught TypeError: (0 , t.createVNode) is not a function

How to decide and why?
