webpack 4升级后的报错怎么解决啊

一直报错，该怎么解决下面这个错误？求指教 

Invalid configuration object. Webpack has been initialised using a configuration object that does no

t match the API schema.

 - configuration has an unknown property 'modules'. These properties are valid:

   object { amd?, bail?, cache?, context?, dependencies?, devServer?, devtool?, entry?, externals?,

loader?, mode?, module?, name?, node?, optimization?, output?, parallelism?, performance?, plugins?,

 profile?, recordsInputPath?, recordsOutputPath?, recordsPath?, resolve?, resolveLoader?, serve?, st

ats?, target?, watch?, watchOptions? }

   For typos: please correct them.

   For loader options: webpack >= v2.0.0 no longer allows custom properties in configuration.

     Loaders should be updated to allow passing options via loader options in module.rules.

     Until loaders are updated one can use the LoaderOptionsPlugin to pass these options to the load

er:

     plugins: [

       new webpack.LoaderOptionsPlugin({

         // test: /\.xxx$/, // may apply this only for some modules

         options: {

           modules: …

         }

       })
