I'm new to vue.js.

I'm trying to render vue component file but when I add to vue component, for example, app/javascript/packs/components/app.vue file, compiling error happens in babel-loader.

error log

ERROR in ./node_modules/babel-loader/lib??ref--1-0!./node_modules/vue-loader/lib??vue-loader-options!./app/javascript/packs/app.vue?vue&type=script&lang=js

Module build failed: ReferenceError: [BABEL] /Users/shiho/dev/appname/app/javascript/packs/app.vue: Unknown option: base.omit. Check out http://babeljs.io/docs/usage/options/ for more information about options.

A common cause of this error is the presence of a configuration options object without the corresponding preset name. Example:

Invalid:

`{ presets: [{option: value}] }`

Valid:

`{ presets: [['presetName', {option: value}]] }`

For more detailed information on preset configuration, please see http://babeljs.io/docs/plugins/#pluginpresets-options.

export default {

Even when I remove presets from .babelrc, same error occurred.

import Vue from 'vue/dist/vue.esm'

import InfiniteLoading from 'vue-infinite-loading';

import Item from './components/Item.vue'

window.onload = function() {

var highlightViewModel = new Vue({

el: '#home-wrapper',

data: {

show: false,

loading: false,

message: '',

items: [],

message: 'helloooo',

},

beforeMount: function () {

var that = this

var params = {

url: '/items/get_timeline.json',

method: 'GET'

}

$.ajax(params).done(function(data){

console.log(data.items);

that.items = data.items;

Vue.nextTick(function () {

$('.timeago').timeago();

});

});

},

components: {

InfiniteLoading,

Item

},
