Question

我正在开发一个laravel项目并尝试添加更少的样式表。

但是，当我从这里更改webpack.min.js时：

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

/*
 |--------------------------------------------------------------------------
 | Mix Asset Management
 |-------------------------------------------------------------------------    -
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.
 |
 */

mix.js('resources/assets/js/app.js', 'public/js')
   .sass('resources/assets/sass/app.scss', 'public/css');

为：

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

/*
 |--------------------------------------------------------------------------
 | Mix Asset Management
 |-------------------------------------------------------------------------    -
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.
 |
 */

mix.js('resources/assets/js/app.js', 'public/js')
   .sass('resources/assets/sass/app.scss', 'public/css');
mix.less('resources/assets/less/main.less', 'public/css');

我的npm停止工作。当我尝试在这些更改后执行 npm run dev 时，我收到以下错误：

> @ dev /Applications/MAMP/htdocs/***.dev
> npm run development


> @ development /Applications/MAMP/htdocs/***.dev
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

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