Question

我正在尝试在我的webpack 3中添加预处理加载程序。我已成功安装它。但它不起作用这是我的webconfing文件

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');
var path = require('path');

module.exports = {
  context: path.join(__dirname, "src"),
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/app.js",
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules|bower_components)/,
        loader: 'babel-loader!preprocess-loader?+DEBUG',
        // query: {
        //   presets: ['react', 'es2015'],
        //   plugins: ['react-html-attrs', 'transform-class-properties', 'transform-decorators-legacy'],
        // }
      },
      {
       test: /\.css$/,
       loader: "style-loader!css-loader!sass-loader"

    }

    ] 

    },
  output: {
    path: __dirname + "/src/",
    filename: "demo.min.js"
  },
  plugins: debug ? [] : [
    new webpack.optimize.DedupePlugin(),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
  ],
};

这是我的package.json
