What does that mean?
What is your ionic info output?

any ionic commond not working

Try removing your node_modules folder and trying again…


thanks i wil try that

i deleted C:\Users\Priyasad\AppData\Roaming\npm\node_modules and reinstall ionic and cordova but still same resoult

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

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

thanks i will install npm 5.5.1

Hi guys i have fixed this issue
it happend becouse of my computer permission issue in program file folder i have uninstalled nodejs and re installed node js to my user folder now it work
