title: Cannot assign to read only property 'prototype' of function 'class Template7
body: <p>I'm following this tutorial to make an app w/ Framework7-Vue.
  <a href="http://blog.toast38coza.me/building-a-mobile-app-with-vuejs-cordova-webpack-and-framework-7/" rel="nofollow noreferrer">http://blog.toast38coza.me/building-a-mobile-app-with-vuejs-cordova-webpack-and-framework-7/</a></p>
  
  <p>For some reason, I see a blank screen once I've copied all the code and installed everything.  I get no errors during compile time.  I get the following error once the app is running in the console</p>
  
  <pre><code>Uncaught TypeError: Cannot assign to read only property 'prototype' of function 'class Template7 {
    constructor(template) {
      const t = this;
      t.template = template;
  
      function getCom...&lt;omitted&gt;...
  }'

  <p>Any ideas what could be causing this?</p>
