they changed the provider into service. try ionic generate service

[pradt]

I suspected that and googled it, but didn't find anything. I was following a tutorial in the end around how to convert a ionic 3 to ionic 4 and it said provider. Thanks jospehlodero, I'll give that a shot.

I added a helpful error message about this change. It will be in 4.0.2. Thanks for the issue!
