【问题描述】：

我试图使用命令“npm run hot”，但没有执行命令，它给了我这个错误：

[webpack-cli] Invalid configuration object. Object has been initialized using a configuration object that does not match the API schema.
 - configuration has an unknown property 'dev'. These properties are valid:
   object { bonjour?, client?, compress?, devMiddleware?, firewall?, headers?, historyApiFallback?, host?, hot?, http2?, https?, liveReload?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, public?, setupExitSignals?, static?, transportMode?, watchFiles? }
npm ERR! code ELIFECYCLE
npm ERR! errno 2
npm ERR! @ hot: `mix watch --hot`

我在这里做错了什么？

日志文件向我显示了这条消息：

最后，这是我的 package.json：

{
    "private": true,
    "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"
    },
    "devDependencies": {
        "axios": "^0.21",
        "laravel-mix": "^6.0.18",
        "lodash": "^4.17.19",
        "postcss": "^8.1.14",
        "vue-loader": "^15.9.5",
        "vue-template-compiler": "^2.6.12"
    },
    "dependencies": {
        "audit": "0.0.6",
        "commander": "^7.2.0",
        "fix": "0.0.6",
        "npm": "^7.12.0",
        "vue": "^2.6.12"
    }
}

我已经尝试了几种来自互联网的方法来解决这个问题，但似乎还没有任何效果。希望有人知道解决这个问题。所有其他命令似乎都很好并且可以执行，只是抛出此错误的“热”命令。

【问题讨论】：

你用的是什么版本的 laravel 和 mix？你也可以分享你的 package.json 吗？
我目前使用的是 Laravel 8.40.0 版、Laravel-mix 6.0.18 版，并且我已经更新了帖子以显示我的 package.json。
这是一个已知问题：github.com/JeffreyWay/laravel-mix/issues/2964
谢谢，为我做的 :)

标签： node.js laravel npm laravel-mix

【解决方案1】：

这是一个已知问题，为了解决这个问题，您必须将以下代码添加到您的 webpack.mix.js：

mix.override(config => {
    // Apply a workaround caused by Laravel Mix using the `webpack-dev-server@v4.0.0-beta`:
    // https://github.com/webpack/webpack-dev-server/releases/tag/v4.0.0-beta.3.
    // Basically the `dev` property has been deprecated in favor of `devMiddleware`.
    if (config.devServer) {
        config.devServer.devMiddleware = config.devServer.dev;
        delete config.devServer.dev;
    }
});
