laravel-mix和webpack：找不到命令

Question

当我运行时，安装正确。在第一个

npm install

上，我得到：npm run dev

到目前为止很好。但是当我再次运行时，我得到了：

    Additional dependencies must be installed. This will only take a moment.

    Running: npm install less-loader less --save-dev --legacy-peer-deps

    Finished. Please run Mix again.

但安装了webpack。这是Laravel-Mix本身的显而易见的依赖性，人们可以在

npm run dev

：

中看到。

> dev
> npm run development

> development
> mix

/bin/sh: webpack: command not found

，确实，他们都在我的

package.lock.json

中。 这是在Laravel 5.8.38和Node23.7.0.

的背景下。 ，什么给？如何解决这个问题？非常感谢

Tldr;

   "webpack": "^5.60.0",
   "webpack-cli": "^4.9.1",
   "webpack-dev-server": "^4.7.3",
   "webpack-merge": "^5.8.0",
   "webpack-notifier": "^1.14.1",
   "webpackbar": "^5.0.0-3",

我的调查

我能够如下所示复制您的问题。

Answer 1

i我能够确认包含webpack的软件包锁。但是，如果我手动安装webpack，则会发生以下错误。

node_modules它似乎是在造成依赖性问题，所以我通过运行

1. Uninstall sass and sass-loader
npm uninstall sass sass-loader

2. Install webpack
npm install webpack --save-dev

3. Run mix
npm run dev

4. Re-run mix since step no.3 asks you to do so
npm run dev

将其删除，然后重新运行

> npm install webpack --save-dev

.

。

当您运行时，Laravel Mix会要求您再次运行，因为它们会尝试重新安装

npm uninstall sass sass-loader和npm install。 npm run dev 前进并重新运行

sass

，这一次应该起作用，因为

sass-loader

和

        Additional dependencies must be installed. This will only take a moment.
 
        Running: npm install sass-loader@^12.1.0 sass --save-dev --legacy-peer-deps
 
        Finished. Please run Mix again.

使用兼容版本

npm run dev

.

。

如果您不确定这有效，请制作原始软件包的副本。

希望这有帮助
