title: VueJs and vue-i18n error
body: <p>im using the Webpack CLI Template.</p>
  
  <p>Then i install <a href="https://kazupon.github.io/vue-i18n/" rel="nofollow noreferrer">https://kazupon.github.io/vue-i18n/</a> with npm install --save vue-i18n</p>
  
  <p>In my main.js i do the import and set the "en" locale</p>
  
  <pre><code>import Vue from 'vue'
  import VueI18n from 'vue-i18n'
  import App from './App'
  import router from './router'
  
  Vue.use(VueI18n)
  Vue.locale('en', {})
  
  new Vue({
    el: '.nwt-mm-app',
    router,
    template: '&lt;App/&gt;',
    components: { App }
  })
  </code></pre>
