title: vue.reactive is not a function
body: <p>I tried to migrate a vue project to a nuxt project. The problem is using <code>store/index.js</code> file.</p>
  <p>I copied the origin file into store folder and this error occurs. I could't find the reason.

  <p><code>store/index.js</code></p>
  <pre class="lang-js prettyprint-override"><code>import { createStore } from &quot;vuex&quot;;
  
  export default createStore({
    state: {},
    mutations: {},
    actions: {},
    modules: {},
  });
  </code></pre>
