Can't build on iOS

I’m doing an app with OneSignal plugin to use push notifications and I have a problem with ios build.

I’m developing from Windows so I’m using ionicframework dashboard to build ios package.

So… I’m getting this error:

/Users/ionic/builds/project-0/platforms/ios/APPNAME/Plugins/onesignal-cordova-plugin/OneSignalPush.h:32:9: 'OneSignal/OneSignal.h' file not found #import 

I use 2 .sh files to use pod.

pod repo update


pod install --project-directory='./platforms/ios/'

What can I do?
