webpack中less-loader6.0.0的javascriptEnabled报错解决

ess-loader6.0.0之前

{
   loader: 'less-loader', 
   options: {
     javascriptEnabled: true 
   }
}

ess-loader6.0.0之后,javascriptEnabled被放到了lessOptions中

{
   loader: 'less-loader', 
   options: {
     lessOptions: {
        javascriptEnabled: true
     } 
   }
}
