Vuejs not reading property from mixins and export NOT FOUND error.

Question

I have been on this error for 3 days, not sure if this is a bug, but I installed vuejs from vuejs/vue-cli

Using the following instructions:

npm install -g vue-cli 
vue init webpack foo.com
cd foo.com
npm install
npm run dev

So far it works, now I created a directory structure like this inside src/

— src
   — assets
   — filters
   — config
   — components
       Profiles.vue
       Login.vue
   profiles.js
   routes.js
   main.js

So, in routes.js I have something like this.

// routes.js
import ProfilesView from './components/Profiles.vue'
import LoginView from './components/Login.vue'

const routes = [{
  path: '/profiles',
  component: ProfilesView 
},
{
  path: '/login',
  component: LogoutView
}]

export default routes

So far, I have no issue with above code, the problem comes from these two below files either profiles.js or Profiles.vue

Here is profiles.js

const profiles = Vue.mixin({
  data: function () {
    return { profiles: [] }
  },
  methods: {
   fetchProfiles: function(){....},
   mounted: function(){ this.fetchProfiles() }
})

export default profiles

Here is Profiles.vue

<template lang="html">
  <div> {{ profiles }}<div>
</template>

<script>
  import { profiles } from '../../profiles'
  export default {
    mixins: [profiles],
    data () {
      return { profiles: [] }
    },
    mounted () {}
  }
</script>

<style lang="css">
</style>

With the above code, I get these errors.

profiles.js:1 Uncaught ReferenceError: Vue is not defined
    at Object.<anonymous> (profiles.js:1)
    at __webpack_require__ (bootstrap 1995fd0fa58cb1432d6f:659)

    at fn (bootstrap 1995fd0fa58cb1432d6f:85)
    at Object.__webpack_exports__.a (app.js:56033)

If I add import Vue from 'vue' to profiles.js the above error gets replaced with this one:

Uncaught TypeError: Cannot read property 'components' of undefined
    at checkComponents (vue.esm.js:1282)
    at mergeOptions (vue.esm.js:1363)
    at mergeOptions (vue.esm.js:1379)

    at fn (bootstrap 625917526b6fc2d04149:85)
    at Object.__webpack_exports__.a (app.js:56036)

This is complaining about the mixins: [profiles], in profiles.js, I am thinking profiles prop is undefined, but that is not the case. For some reason Profiles.vue is not reading or reading the correct data from profiles.js because I also get this error always:

[HMR] bundle has 1 warnings
client.js:161 ./~/babel-loader/lib!./~/vue-loader/lib/selector.js?type=script&index=0!./src/components/Profiles.vue
6:11-15 "export 'profiles' was not found in '../../profiles'

It is complaining export default profiles isn't found in profiles.js even though it clearly does. I even tried using require, changing the paths ... everything. Nothing works.

I would appreciate any help with this.

You are importing profiles.js in the wrong way:

import { profiles } from '../../profiles'

Since you are using export default, it should be

import profiles from '../../profiles'
