刚刚新建了一个webpack demo，想使用jshint来检测自己的js代码，发现总是提示
Cannot find module 'jshint
在执行多次的npm install jshint-loader --save-dev依然报错，作为新手想让大家帮我瞅瞅！

module代码如下：

module.exports = {
module: {
loaders: [
  {
    test: /\.css$/,
    loaders: ['style', 'css?sourceMap'],
    include: APP_PATH
  },
  {
    test: /\.(png|jpg)$/,
    loader: 'url?limit=40000'
  },
  {
    test: /\.jsx?$/,
    loader: 'babel',
    include: APP_PATH,
    query: {
      presets: ['es2015']
    }
  }
],
preLoaders: [
    {
        test: /\.jsx?$/,
        include: APP_PATH,
        loader: 'jshint-loader'
    }
]
},
jshint: {
  "esnext": true
}
};

此时运行npm start,便出现下面的错误截图：
