title: Laravel 5.4 and Axion making me crazy: "Axios is not defined"
body: <p>I'm running Laravel 5.4 with Vue.js and Axios with Laravel Passport. So in my /home I call Vue.js components:</p>
  
  <pre><code>&lt;passport-clients&gt;&lt;/passport-clients&gt;
  &lt;passport-authorized-clients&gt;&lt;/passport-authorized-clients&gt;
  &lt;passport-personal-access-tokens&gt;&lt;/passport-personal-access-tokens&gt;
  </code></pre>
  
  <p>When I run the server and got into page, the components are loaded. However, the action buttons doesn't work and this error's appears:</p>
  
  <blockquote>
    <p>vue.js?3de6:482 [Vue warn]: Error in mounted hook: "ReferenceError: axios is not defined" found in --->  at /home/someusername/Documentos/AGIL/DESENVOLVIMENTO/somefolder/projeto/resources/assets/js/components/passport/Clients.vue
           </p>
  </blockquote>
  
  <p>And other's, such as:</p>
  
  <blockquote>
