Having error when add Device in provider

#1

Hello!
I would like to use the ionic Device plugin to get the IMEI of the device on which my application is running.
I managed to install the plugin but when I try to add it in the providers, I have the error:
Type ‘DeviceOriginal’ is not assignable to type ‘Provider’.
Type ‘DeviceOriginal’ is missing the following properties from ‘FactoryProvider’ type: provide, useFactory [2322]

here is the information of my environment:
