npm i style-resources-loader -D

 function generateLoaders (loader, loaderOptions) {
 const loaders = options.usePostCSS ? [cssLoader, postcssLoader] : [cssLoader]

 if (loader) {
  loaders.push({
  loader: loader + \'-loader\',
  options:  .assign({}, loaderOptions, {
   sourceMap: options.sourceMap
  })
  })
 }

 // Extract CSS when that option is specified
 // (which is the case during production build)
 if (options.extract) {
  return ExtractTextPlugin.extract({
  use: loaders,
  fallback: \'vue-style-loader\'
  })
 } else {
  return [\'vue-style-loader\'].concat(loaders)
