undefined @deprecate decorator

I'm trying to import magpy and I'm receiving errors that the @deprecate decorator is not defined. This is the error I'm getting below. MagPyLib 1.1.7. Is this a compatibility issue of some kind? I've worked around by commenting out the decorator, I don't need relevant functionality.
