Can't use vue component in my Rails5 app

问题

I'm new to vue.js and webpack configuration.

I can use Vue instance in app/javascript/packs/somecode.js.

But I can't render *.vue file. If I add any *.vue file to app/javascript/packs/components/ directory,

it says

"module build failed: ReferenceError: [BABEL] A common cause of this error is the presence of a configuration options object without the corresponding preset name. ".

But I didnt create any new option.

environment

ruby

ruby 2.4.3p205 (2017-12-14 revision 61247) [x86_64-darwin16]

rails

5.1.0

app.vue

<script>
export default {
  data: function () {
    return {
      message: "Hello Vue!"
    }
  }
}
</script>

console.log in my chrome browser

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.
