rxjs/Subscription has no exported member 'ISubscription'

Question

I'm migrating from angular 5 to angular 6. When I make npm run build, I'm it is throw to the console the following error:

ngc compilation failed: ng-formly/core/src/components/formly.field.ts(10,10): error TS2305: Module '"C:/PrjNET/Elevation3/FW/4.00/Mainline/Framework/Development/Client/ElevationJS/ngcore/.tmp/node_modules/rxjs/Subscription"' has no exported member 'Subscription'.

I had a similar error: rxjs/Subscription has no exported member Subscription and I solve by importing Subscription like this:

import { Subscription } from "rxjs";

But I cannot do the same to ISubscription.

Any one knows how can import ISubscription ?

Answer 1

In RxJS v6, ISubscription was renamed to SubscriptionLike, as that's the convention used in Typescript's own type declarations.

Similarly, IScheduler was renamed to SchedulerLike.
