Problem :

I have recently started learning about Vue. Please find below my main javascript file:

import Vue from 'vue'

new Vue({

  myel: '#app'


Please find below my HTML file:


    <div id="app"></div>

    <script src="{{ mix('/js/app.js') }}"></script>


Please find below my webpack configuration of Vue.js with a runtime build:

alias: {

    'vue$': 'vue/dist/vue.runtime.common.js'


But I am facing below listed very well known error:

Failed to mount component: template or render function not defined.

Why am I getting above error when I clearly do not have any thing inside a #app div where I am trying to mount Vue and still facing the template or render error?

How can I fix above error?

Solution :

I can surely fix your issue as I had faced this issue in the past and after making lot of efforts I managed to find solution on it. I was using the Typescript with vue-property-decorator and what happened with me was that my IDE auto-completed "TheComponent.vue.js" instead of "TheComponent.vue". That was the reason behind this error.

So I can surely say that the moral of a story is by any chance if you face above error and if you are using any of the single-file component setup then you must cross check your imports in your router.
