After installing geolocations there are errors

Hi so I’m woking on a project that needs to use geolocations and after I installed the geolocations (I used the exact steps that was provided in the documentations) but I’m getting this error when I try to build the app on the iOS platform and here is the error :

[21:29:50]  typescript: node_modules/@ionic-native/geolocation/index.d.ts, line: 1 
            Module '"/Users/mr3bood/Desktop/dev/myApp-master/node_modules/@ionic-native/core/index"' has no exported 
            member 'IonicNativePlugin'. 

       L1:  import { IonicNativePlugin } from '@ionic-native/core';
       L2:  import { Observable } from 'rxjs/Observable';

I think you should up your ionic-native/core to at least 3.6.0 . This is probably due to a mismatch in versions (plugin you installed is way newer then your core version). Change the version accordingly in your package.json, remove your node_modules and run npm install again. Let me know if it worked out.
