我安装了一个新的laravel 5.4应用程序。我按照文档介绍了如何设置laravel mix。但是，当我运行npm run dev时，我收到以下错误：

我明白了。感谢Andy Holmes。我不得不在hometead中更新我的nodejs，运行以下命令
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs
然后我运行以下命令来重建node-sass
npm rebuild node-sass

我删除了整个node_modules文件夹并尝试使用yarn而不是npm安装软件包。
删除node_modules文件夹
使用纱线重新安装包裹，例如 run yarn instead of npm install.
我希望这有助于某人。
答案 2 :(得分：0)
如果你看第2行和第3行就可以看到节点和npm
2 info using npm@3.8.6
3 info using node@v5.12.0
在第23行中期：
23 error If you do, this is most likely a problem with the package,
23 error not with npm itself.
答案 3 :(得分：0)
我不知道为什么会这样，是否是一个特定的版本有一个已修复的bug，但是为了让我的新laravel 5.4安装工作，我必须更改包中的路径.json来自：
node_modules/cross-env/bin/cross-env.js
到
node_modules/cross-env/dist/bin/cross-env.js
注意添加“dist”
修改
实际上注意到新的全新安装
node node_modules/cross-env/bin/cross-env.js
简单地用
替换cross-env
例如：
"scripts": {
"dev": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},
