复制步骤：

清洁拉维安装( 编写器创建项目（laravel/laravel Web界面）

遵循以下步骤：

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install

这是你的电话号码

我在我的根目录中使用了下面的代码，问题得到了解决

sudo npm install -g PACKAGE-NAME --unsafe-perm=false --allow-root

我在下面安装了所有的软件包

sudo npm install -g --unsafe-perm=false --allow-root 

Npm现在运行良好

感谢您的帮助。

应将webpack dev服务器降级为：

npm install --save-dev webpack-dev-server@2.9.7

npm install --save-dev webpack-dev-server@2.9.7
