Can you please help me…

What is your ionic info output in the project folder?

That has absolutely nothing to do with ionic info. You have to run that command in the project and post the output here.

From the photo seems like you should run cmd as administrator. Also in the reference try left click and restore package or build project.

i think you use latest node version 10.6.0 as shown in your error
install LTS version of node and then try

ya i tried but it not working

Your problem is probably with npm, something to do with permissions and files. This happens quite often and is almost impossible to successfully debug (at least here in the forum).

One solution: Uninstall your node, install nvm (or nvm-windows if you are on Windows), install a new node (which includes npm) with this, then install ionic and cordova again and try your command again. The problem should be gone.
