Try removing your node_modules folder and trying again…

C:\Users\Priyasad\AppData\Roaming\npm\node_modules

Reinstall of NodeJS perhaps? That first error message re CALL node.exe should be recognised.

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.

I did everything as you said but still same issue

11

your npm version 5.6.0 could have some issues with ionic. i am using npm 5.5.1 without any issue

12

thanks i will install npm 5.5.1
