Laravel Mixで開発をしていおります。
下記のようなpackage.jsonの設定をしており、developmentビルドではエラーも何も発生せず正常に処理が出来ております。
package.json

{
  "private": true,
  "scripts": {
    "dev": "npm run development",
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
  },
  "devDependencies": {
    "@voerro/vue-tagsinput": "^1.11.2",

  },

    "vue-observe-visibility": "^0.4.3",
    "vue-qriously": "^1.1.1",
    "vuex": "^3.1.0"
  }
}

ただ、npm run prodとし、production用のビルドを走らせると、下記のようなcss-loaderのエラーが出てしまっております。

ERROR in ./node_modules/css-loader/dist/cjs.js?minimize!./node_modules/vue-loader/lib/style-compiler?{"vue":true,"id":"data-v-6434f8e0","scoped":true,"hasInlineConfig":true}!./node_modules/sass-loader/lib/loader.js!./node_modules/vue-loader/lib/selector.js?type=styles&index=0!./resources/assets/js/components/Loading.vue

こちらのサイトなどを参考に、css-loaderが悪さをしていそうなところまではわかったのですが、developmentとproductionで結果が違うのがなぜなのか、原因がわからずでおります。

どなたか、原因・解決策をご存知の方がいらっしゃいましたら、ご教授頂けますと幸いでございます。

何卒、よろしくお願いいたします。
