FIXED：的解决办法是删除该文件夹node_modules并重新运行NPM INSTAL，并在此之后一切工作。Laravel 5.4 NPM运行dev的错误

我有一些问题Laravel并试图运行 “故宫运行dev的”，我得到这个错误：

我NPM的版本和节点是：

NPM：4.5。 0 节点：v7.8.0

而Laravel 5.4

这里是我的packages.json：

{ 
    "private": true, 
    "scripts": { 
    "dev": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", 
    "watch": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", 
    "watch-poll": "node node_modules/cross-env/dist/bin/cross-env.js 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": "node node_modules/cross-env/dist/bin/cross-env.js 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": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js" 
    }, 
    "devDependencies": { 
    "axios": "^0.15.3", 
    "bootstrap-sass": "^3.3.7", 
    "cross-env": "^3.2.3", 
    "jquery": "^3.1.1", 
    "laravel-mix": "0.*", 
    "lodash": "^4.17.4", 
    "vue": "^2.1.10" 
    }, 
    "dependencies": { 
    "webpack": "^2.3.3" 
    } 
}

任何解决方案？

你有你的根目录下的'webpack.mix.js'文件？ –

你在Windows机器上运行吗？ https://laravel.com/docs/5.4/mix#running-mix =>删除文件夹node_modules并重新运行NPM安装这样的：NPM安装--no斌链接 –

我在webpack.mix.js我的根，在这里没有改变任何东西。还我运行的Mac –

答

我做laravel的全新安装，更新了我的节点和故宫和所有工作正常，按照这些步骤

npm install 
npm install cross-env -D 
npm run dev
