Current behavior:

We are going to be moving to Angular 6 and rxjs 6 for ionic-angular v4. Currently, because of breaking changes in rxjs, the current release of ionic-native will cause the ng cli to break with the following errors:

ng] ERROR in node_modules/@ionic-native/core/decorators.d.ts(1,10): error TS2305: Module '"C:/Users/jgw96/Projects/ionic-conference-app/node_modules/rxjs/Observable"' has no exported member 'Observable'.
[ng] node_modules/@ionic-native/core/plugin.d.ts(2,10): error TS2305: Module '"C:/Users/jgw96/Projects/ionic-conference-app/node_modules/rxjs/Observable"' has no exported member 'Observable'.
[ng] node_modules/@ionic-native/in-app-browser/index.d.ts(2,10): error TS2305: Module '"C:/Users/jgw96/Projects/ionic-conference-app/node_modules/rxjs/Observable"' has no exported member 'Observable'. 

Steps to reproduce:

• grab the core-update branch of the conf app https://github.com/ionic-team/ionic-conference-app/tree/core-update
• remove rxjs-compat from the package.json
• run npm install
• run ionic serve with the latest rc of the ionic cli

@danielsogl When will this be released?

[danielsogl]

We will release Ionic Native V5 together with Ionic V4. If you need rxjs 6 support you can use the latest v5 beta.

Adding my two cents. My ionic angular electron project when updating dependencies:

[10:39:56]  typescript: A:/project/node_modules/rxjs/Observable.d.ts, line: 1
            Cannot find module 'rxjs-compat/Observable'.

       L1:  export * from 'rxjs-compat/Observable';

I want to fix this properly but I've been breaking a lot of existing projects lately messing around while learning these building technologies...so... yarn add rxjs-compat 😸

Would this fix 'properly' if I installed the latest @ionic/angular (_disambiguation_ not ionic-angular?) or do I need to run yarn add for all latest versions of @ionic packages?
