I tried uninstalling and installing nodejs and ionic/cordova two times but getting the same result. When i tried ionic 2 before worked perfect, but not after update to last version.

Any help? Thanks!

P.S: i have Windows 10 x64

Answer

I found the solution.

I updated nodejs to version 5.8.0 from version 4.

Apart from this, I manually removed the npm-cache folder. I think npm cache clean did not work.
