Bootstrap-vue doesn't load CSS : <p>I am writing a Vue.js app with Bootstrap 4 and I can't loaded though I followed the documentation.</p>

<p>Added to main.js</p>

<p><code>Vue.use(BootstrapVue);</code></p>

<p>Added to css file related to App.vue:</p>

<pre><code>@import '../../node_modules/bootstrap/dist/css/bootstrap.css';
@import '../../node_modules/bootstrap-vue/dist/bootstrap-vue.css';
</code></pre>

<p>Here is template:</p>

<pre><code>&lt;div class="main"&gt;
&lt;div&gt;

    &lt;b-modal id="modal1" title="Something went wrong" v-if="!serverStatusOk"&gt;
        &lt;p class="my-4"&gt;{{msg}}&lt;/p&gt;
        &lt;p class="my-4"&gt;{{statusCode}}&lt;/p&gt;

    &lt;/b-modal&gt;
&lt;/div&gt;

&lt;div&gt;
    &lt;b-tab title="Players" active&gt;
        &lt;br&gt;Players data
    &lt;/b-tab&gt;
    &lt;b-tab title="Tournaments" active&gt;
        &lt;br&gt;Tournament data
    &lt;/b-tab&gt;
&lt;/div&gt;
</code></pre>

<p></p>

<p>Result: no css rendered but in css file from dist dir I see Bootstrap
What am I missing? The project created by vue-cli 3.0-beta</p>
