Laravel 5.4 Vue.JS Failed to mount component: template or render function not defined

It should be require('./components/Example.vue').default. Since v13, vue-loader exports the component as the default key, which still works the same when using import, but requires the above when using require.

Try this

Vue.component('example-component', require('./components/ExampleComponent.vue').default);

As of now, the plaster I have is to add a 'default()' to all Vue object's component.

Vue.component('form-component', require('./components/FormComponent').default);
Vue.component('gratitude-pop', require('./components/GratitudePop').default);//..etc..etc

Running this package:
