如何使用webpack.mix.js編譯純CSS

我正在使用Laravel 8 PHP 框架，我需要使用node在localhost上編譯JS和CSS檔案。當我試圖運行錯誤輸出是：npm run dev

$ npm run dev

> dev
> npm run development


> development
> mix

}

我怎么看，問題出在mix檔案中，錯誤的語法會是一個問題嗎？

這是代碼

const mix = require('laravel-mix');

mix.js('resources/js/app.js', 'public/js')
    .js('resources/assets/js/bootstrap.js', 'public/js')
    .js('resources/assets/js/core.min.js', 'public/js')
    .js('resources/assets/js/script.js', 'public/js')
    .js('resources/assets/js/slider.js', 'public/js')
    .js('resources/assets/js/html5shiv.min.js', 'public/js')
    .js('resources/assets/js/jquery-3.6.0.min.js', 'public/js')
    .js('resources/assets/js/pointer-events.js', 'public/js');

mix.styles([
    'resources/assets/css/bootstrap.css',
    'resources/assets/css/bootstrap-grid.css',
    'resources/assets/css/bootstrap-utilities.css'
],'public/css');

mix.styles([
    'resources/assets/css/app.css',
    'resources/assets/css/util.css'
], 'public/css');

為此，我使用Laravel 7 Docs ，因為我在Laravel 8 Docs中沒有找到任何內容

我沒有使用 sass或scss，因為源專案每個檔案有大約 30000行css行，我不知道如何轉換它。

這是package.json檔案

{
  "dependencies": {
    "bootstrap-icons": "^1.7.2",
    "cross-env": "^7.0.3",
    "laravel-mix": "^6.0.39"
  },
  "scripts": {
      "dev": "npm run development",
      "development": "mix",
      "watch": "mix watch",
      "watch-poll": "mix watch -- --watch-options-poll=1000",
      "hot": "mix watch --hot",
      "prod": "npm run production",
      "production": "mix --production"
  }
}

uj5u.com熱心網友回復：

您必須將檔案作為第二個引數而不是檔案夾傳遞。所以：

    mix.styles([
        'resources/assets/css/bootstrap.css',
        'resources/assets/css/bootstrap-grid.css',
        'resources/assets/css/bootstrap-utilities.css'
    ],'public/css/bootstrap.css');
    
    mix.styles([
        'resources/assets/css/app.css',
        'resources/assets/css/util.css'
    ], 'public/css/app.css');
