I'm trying to follow this instruction <https://webpack.js.org/loaders/jshint-loader/>
and get an error:

My config file: 

```js
const path = require('path');

    module.exports = {
      entry: {
        app: './index.js'
      },
      output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist')
      },

      module: {
        rules: [
          {
            test: /\.js$/, // include .js files
            enforce: "pre", // preload the jshint loader
            exclude: /node_modules/, // exclude any and all files in the node_modules folder
            use: [
              {
                loader: "jshint-loader"
              }
            ]
          }
        ]
      },

      // more options in the optional jshint object
      jshint: {
        // any jshint option http://www.jshint.com/docs/options/
        // i. e.
        camelcase: true,

        // jshint errors are displayed by default as warnings
        // set emitErrors to true to display them as errors
        emitErrors: false,

         // jshint to not interrupt the compilation
         // if you want any file with jshint errors to fail
         // set failOnHint to true
         failOnHint: false,

         // custom reporter function
         reporter: function(errors) { }
       }
    };
```
