toastr.info is not a function

[developer-pta]

Hi
I can't get toastr to work...
I'm using Aurelia and typescript.
With import like this:
import toastr from "toastr";
I get error: app.ts:17 Uncaught (in promise) TypeError: Cannot read property 'info' of undefined.

With import like this:
import * as toastr from "toastr";
I get error: Uncaught (in promise) TypeError: toastr.info is not a function

The usage pattern is: toastr.info("Test");

also tried
import {default as toastr} from "toastr";
which gave me error: Uncaught (in promise) TypeError: Cannot read property 'info' of undefined.

How to get it to work properly?

The problem is not in toastr, but the module loader I use.
