VueのSPCのstyleがwebpackでロードされない

Vueで作ったやつをwebpackでビルドするのに失敗します。Curry.vueという単一ファイルコンポーネントの中のstyleが処理できないようです：

<style scoped>
.tomato {
    color: red;
}
</style>

エラーメッセージは下記です：

ERROR in ./src/components/Curry.vue?vue&type=style&index=0&id=4d934a99&scoped=true&lang=css& (./node_modules/vuetify-loader/lib/loader.js??ref--7-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/Curry.vue?vue&type=style&index=0&id=4d934a99&scoped=true&lang=css&) 111:0
Module parse failed: Unexpected token (111:0)
File was processed with these loaders:
 * ./node_modules/vuetify-loader/lib/loader.js
 * ./node_modules/vue-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.

私のwebpack.config.jsは下記です：
