 var webpack = require('webpack');
var path = require('path');
module.exports = {
    context: path.join(__dirname, 'src'),
    entry: ".src/js/index.js",
    resolve: {
    //  第一项空字符串必不可少，否则报模块错误
    extensions: ['', '.es6','.js','.jsx']
  },
  module: {
    loaders: [{
      test: /\.js?$/,
      exclude: /node_modules/,
      loader: 'babel-loader',
      query: {
        presets: ['react', 'es2015']
      },
    }]
  },

  output: {
    // path: path.resolve(__dirname, 'dist'),
    path: __dirname,
    filename:'./src/bundle.js'
  }
}

  课程的 webpack 配置https://github.com/ParryQiu/IMOOC-React/blob/master/react-router-4_webpack-2-CP22/webpack.config.js
  这是 2.0 的 webpack 配置
  源码中也有 1.0 的配置。

  throw new Error(
          ^
  
  Error: original.line and original.column are not numbers -- you probably meant to omit the original mapping entirely and only map the generated position. If so, pass null for the original mapping instead of an object with empty or null values.

  将
  https://github.com/ParryQiu/IMOOC-React/blob/master/react-router-4_webpack-2-CP22/webpack.config.js 
  配置复制到我自已的webpack.config.js中时，提示发上所示的错误
  这些错误，是表示什么？
