使用npm run dev 运行一个新的vue项目时，报错如下：

sh: 1: webpack-dev-server: Permission denied
npm ERR! code ELIFECYCLE
npm ERR! errno 126

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

解决办法： 卸载npm uninstall webpack-dev-server，安装npm i webpack-dev-server@2.9.7

在运行，成功启动。如有更好的解决方案欢迎指正！
