npm install报错-The operation was rejected by your operating system

The operation was rejected by your operating system.It’spossible that the file was already in use(by a text editor or antivirus),or that you lack permissions to access it.If you believe this might be a permissions issue,please double-check the permissions of the file and its containing directories,or try running the command again as root/Administrator.

解决办法：
删除本机电脑用户目录下的.npmrc文件
EG:C:\Users(用户名).npmrc
