Please help.

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 when you are using Windows), install a new node with this, then install ionic and cordova again and try your command again. The problem should be gone.

Thank you very much. It works fine again. I do the following:

npm uninstall npm -g

install nvm for Windows from here: (Version 1.1.5 -

using Node-version 6.9.4

Install Cordova with:

npm install -g cordova

Install Ionic (specific Version) with:

npm install -g ionic@2.2.3
