Webpack fails with babel has been moved to babel-core

Question

I've followed the solutions on stackoverflow posts posted by different developers. However, none of them helped fix the issue I'm encountering. Few of the things I did are

1. uninstall babel
2. install babel-core, babel-cli
3. upgraded to node v6.2.2
4. reinstall webpack
5. blew up node_modules and ran npm install again

All of the above never fixed this error

webpack: bundle is now VALID.

Here is my package.json

{
  "name": "react-es6-setup",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.2.0",
    "react-dom": "^15.2.0"
  },
  "devDependencies": {
    "babel-core": "^6.10.4",
    "babel-loader": "^6.2.4",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.11.1"
  }
}

And webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    path: './',
    filename: 'index.js'
  },
  devServer: {
    inline: true,
    port: 3333
  },
  module: {
    loaders: [
        {
          test: /\.js$/,
          exclude: 'node_modules',
          loader: 'babel',
          query: {
            presets: [ 'es2015', 'react' ]
          }
        }
    ]
  }
}

and the dir listing of the node_modules

$ ls -l node_modules/ |grep react

Having loaders: 'babel-loader' in webpack.config.js fixed the issue for me-

install these dependencies using npm

"babel-core": "^6.1.2",
"babel-loader": "^6.1.0",
"babel-plugin-transform-runtime": "^6.1.2",
"babel-preset-es2015": "^6.1.2",
"babel-preset-stage-0": "^6.1.2",
"babel-runtime": "^5.8.0",

In webpack.config.js file, have this code:

const path = require('path');
module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'dist.js',
    publicPath: "js"
  },
  module: {
    loaders: [
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      }
    ]
  }
}
