vue strap styles are not working

[kiruh]

I'm trying to add alert to the App.vue file

<template>
    <div id="app">
        <alert>
            <strong>Well Done!</strong>
            <p>You successfully read this important alert message.</p>
        </alert>
    </div>
</template>

<script>
    import { alert } from 'vue-strap';
    export default {
        name: 'app',
        components: {
            alert
        },
    }
</script>

but styles do not work on the page I ran commands: npm install bootstrap@4.0.0-alpha.6 --save-dev npm install vue-strap --save

I'm using webpack as a bundler. What should I do to configure it correctly?

Right now vue-strap only support bootstrap 3.
