` __webpack_require__(...) is not a function` when using babel 6

Question

Everything seems to build fine: http://d.pr/i/1aZxR with the following configs.

However, when I run the code I get the following error this (via webpack-dev-server):

Uncaught TypeError: __webpack_require__(...) is not a function(anonymous function) @ login.js:4__webpack_require__ @ bootstrap 38790ff45722f55eb700?6a08:50(anonymous function) @ bootstrap.js:2363__webpack_require__ @ bootstrap 38790ff45722f55eb700?6a08:50(anonymous function) @ app.38790ff45722f55eb700.js:29__webpack_require__ @ bootstrap 38790ff45722f55eb700?6a08:50webpackJsonpCallback @ bootstrap 38790ff45722f55eb700?6a08:21(anonymous function) @ app.38790ff45722f55eb700.js:1

I think babel is interfering with __webpack_require__ in some way but I'm not sure. I did try using different transforms/plugins but I wasn't able to find a solution.

.babelrc:

{
  "plugins":[
    "transform-runtime",
    "transform-node-env-inline"
  ],
  "presets":[
    "stage-0",
    "es2015"
  ]
}

here's my webpack.config.js:

var Clean = require('clean-webpack-plugin');
var CompressionPlugin = require("compression-webpack-plugin");

Answer 1

I'd like to add another reason why this error might pop up:

I did the following:

import mapActions from 'vuex'

instead of:

import { mapActions } from 'vuex'

The former was importing the entire vuex export, which is an object. Adding object destructuring fixed the problem.
