所以我有一个laravel 5.4项目，当我运行npm install dev时，我收到以下错误
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 /安装/ webpack.config.js`
这是我的package.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",

"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": {

"lodash": "^4.17.4",
"react": "^15.4.2",
"react-dom": "^15.4.2",
"vue": "^2.1.10"
}
}
为什么我会收到此错误？
答案 0 :(得分：0)
运行此命令：
npm install --global cross-env
并在“devDependencies”
下的package.josn中添加"gulp": "^3.9.1"
这可能对您有所帮助

我有相同的问题，并且您将其替换为package.json

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install
npm run dev
希望这对您有所帮助。

因为您正在尝试安装依赖项。
安装devDependencies，你可以做
npm install --only=dev
要运行dev，你可以
npm run dev
