Question

我正在研究Laravel项目。我已经从头开始安装了Laravel项目。我的笔记本电脑的操作系统是Windows 10。我已经安装了npm install。然后我运行“ npm run dev”。然后出现以下错误。

> @ development C:\Users\Acer\Desktop\LaravelProjects\PatheinDirectory
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

C:\Users\Acer\Desktop\LaravelProjects\PatheinDirectory\node_modules\cross-env\src\index.js:87
  const envVars = {...process.env}
                   ^^^

我尝试删除node_modules文件夹，然后尝试再次运行npm run dev。它没有用。

我也尝试在删除了node_modules文件夹后运行以下命令。

npm install --global cross-env

它也不起作用。我该如何解决？

Answer 1

运行npm cache clean，然后重试

Answer 2

尝试更新npm。我遇到了同样的错误，对我有用。

如果您使用的是nvm，请阅读here有关更新的信息
