title: Can not use nuxt-i18n (version 5.4.2)
body: <p>In my Nuxt.js application, I want to use the newest version (5.4.2) of <a href="https://nuxt-community.github.io/nuxt-i18n/" rel="nofollow noreferrer">nuxt-i18n</a>. I used it previously without any problems, but I do not understand what is going wrong now:</p>
  
  <h3>Version</h3>
  
  <p><a href="https://github.com/nuxt-i18n/releases/tag/v5.4.2" rel="nofollow noreferrer">v5.4.2</a></p>

  <p><a href="https://github.com/begueradj/nuxti18nerror" rel="nofollow noreferrer">https://github.com/begueradj/nuxti18nerror</a></p>
  
  <h3>Steps to reproduce</h3>
  
  <ol>
  <li>Either clone my project and follow the README file instructions</li>
  <li>Or create the a Nuxt.js project: <code>yarn create nuxt-app my-project</code>, then install the plugin: <code>yarn add nuxt-i18n</code> , then add it to the configuration file <code>nuxt.config.js</code>  as the official documentation says:  <code>modules: [  ['nuxt-i18n', {    // Options   }] ]</code></li>
  </ol>
  
  <h3>What is expected ?</h3>
  
  <p>I expect to launch the server without errors when I run <code>yarn run dev</code>. As simple as that.</p>
  
  <h3>What is actually happening?</h3>
  
  <p>When I run <code>yarn run dev</code> I am getting this error message:</p>
