error 'cannot find module' on 'main.scss' with Webpack, SASS, and React

Question

When trying to set up SCSS to run the styling on my React application using Webpack I am presented with the error:

Module not found: Error: Can't resolve 'style' in '/Users/sachinkaria/Workspace/GC' @ ./app/index.js 4:0-29 @ multi ./app/index.js'

and in the browser:

Uncaught Error: Cannot find module "/styles/main.scss"

My webpack.config.js configuration is below:

var HtmlWebpackPlugin = require('html-webpack-plugin');-
var HTMLWebpackPluginConfig = new HtmlWebpackPlugin({
  template: __dirname + '/app/index.html',
  filename: 'index.html',
  inject: 'body'
});

module.exports = {
  entry: [
    './app/index.js'
  ],
  output: {
    path: __dirname + '/dist',
    filename: "index_bundle.js"
  },
  module: {
    loaders: [
      {test: /\.js$/, exclude: /node_modules/, loader: "babel-loader"},{
            test: /\.scss$/,
            loaders: ['style', 'css', 'sass']
        }
    ]
  },
  plugins: [HTMLWebpackPluginConfig]
};

My package.json:

    {
  "name": "get-cooked",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server",
    "prod": "webpack -p"
  },

  },

    "sass-loader": "^6.0.2",
    "webpack": "2.2.1",
    "webpack-dev-server": "^1.14.1"
  }
}

My index.js where I am importing the main.scss (producing the error):

var React = require('react');
var ReactDOM = require('react-dom');
var routes = require('./config/routes');
require('./styles/main.scss');

ReactDOM.render(routes, document.getElementById('app'));

All my scss files are in my styles folder, however, I can't seem to import them into my index.js and am returned with the 'Cannot find module' error.'

Here is my folder structure:

- app
  - components
    - Home.js
  - config
    - routes.js
  - containers
  - styles
    - components
    - main.scss
  - index.html
  - index.js
- nodemodules
webpack.config.js
package.json

Any help appreciated!

Replace /styles with

./styles 

if index.js and styles are in the same folder

EDIT: If you're coming from Google - turns out style-loader and css-loader were not installed, make sure of that as well.
