Everything is in the error message, you probably did an npm install using administrator rights and now it needs to remove/rename folders but it doesn't have permissions for that. – Supamiu
Supamiu , I installed with administrator privileges only but when I tried to install the dependencies again I am getting the error so I deleted the node modules folder and then installed again and its working. – Nasrul Bharathi

When we already have node modules then when we give "npm install" it will check all the dependencies and if it is already present then it will ignore and install only those which is not present. Sometime it will throw such an error.Not sure why it happens but I deleted the node modules folder and then installed again and its work perfectly.
