You may need an appropriate loader to handle this file type.

i don't know how i can solve my webpack looks like this

'use strict';

var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  devtool: 'inline-source-map',
  entry: [
    'webpack-hot-middleware/client?reload=true',
    path.join(__dirname, 'src/App.js')
  ],
  output: {
    path: path.join(__dirname, '/dist/'),
    filename: '[name].js',
    publicPath: '/'
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: 'src/index.html',
      inject: 'body',
      filename: 'index.html'
    }),
    new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('development')
    })
  ],
  module: {
    loaders: [{
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'babel',
      query: {
        "presets": ["react", "es2015", "stage-0", "react-hmre"]
      }
    }, {
      test: /\.json?$/,
      loader: 'json'
    },

      {
        test: /\.scss$/,
        loader: 'style!css!resolve-url!sass?sourceMap'

        }
      }
    ]
  },

check your loader path ,maybe you're loader path was wrong.
like this:

{
            test: /\.scss$/,
            exclude: /^node_modules$/,
            loader: 'style-loader!css-loader!autoprefixer-loader!sass-loader',
            include: [pathConfig.include_ptah]
}

check your include path
