Typescript incompatible type when using NgForage as storage

[owi1972]

I try to use NgForage as a storage engine in Anguar 5
import { NgForage, NgForageModule} from ngforage/ngforage-ng5;
But I get a Typescript incompatible type error - any hints how to fix this?

Do not use ngforage, just import
import localForage = require("localforage");
