I had the same issues. Your ionic/core module is wanting Angular 5, which will have “metadata” version of 4.

You can upgrade to ionic 3.9.2 and angular 5.2.11 (worked for me), better option.
Or downgrade the ionic core module to one that wants angular 4.

This has nothing to do with the cordova version, its the angular compiler (ngc)
