【问题描述】：
对npm run 的任何调用都会产生此错误：
$ npm run dev
> @ dev /project
> npm run development
> @ development /project
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js
/project/node_modules/webpack-cli/bin/cli.js:235
throw err;

这是我的 package.json：

我的webpack.mix.js：
const mix = require('laravel-mix');
mix.js('resources/assets/js/app.js', 'public/js')
.sass('resources/assets/sass/app.scss', 'public/css')
.version()
.sourceMaps();
我已尝试再次删除 node_modules 和 npm install，但这并不能解决问题。
rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install
使用yarn install 而不是 npm 执行相同的过程并不能解决问题。
尝试使用此选项进行安装，但没有成功：npm install node-sass --no-bin-links
- npm v6.4.1
- 节点 v11.5.0
- yarn v1.12.3
这个问题在旧版本的 Webpack 和 Mix 上不会发生。例如，以下软件包可以工作，但显然失去了一些新功能：
"laravel-mix": "^3",
"webpack": "^3.11.0",
"webpack-cli": "^3.1.2"
