i have the same error .... in my app ...
but:

I've changed index.d.ts, at line 232,
From : export abstract class Notice extends NoticeProperties
To : export default abstract class Notice extends NoticeProperties

and the error go away .... i think that, we have two abstract classes declared in this file, however, angular doesn't know what class is the "main" class of the file.

i think that it's the answer!
See ya

Hi,
Thanks for reply (I go to modify in node_modules) but what the developer think about these issues ?
Do they will be fixed in the next version to fit with angular 9 ?

#399
#398

Managed to recreate this on codesandbox.io with Angular 11.2 which is interesting because no errors are thrown there, which is why I think this was overlooked

Easy way recreate this issue:

1. ng new PNotifyTest
2. npm i --save pnotify
3. (Add code either from the PNotify Angular docs or from the provided codesandbox.io example)
4. ng s

I'm looking into this now.

Is this only happening with Angular, or with any project using TypeScript?

Can't say for sure, I think everyone who commented here experienced it with Angular projects -
I suspect Typescript projects may be affected too

Since Svelte now supports TypeScript natively, I may be able to do away with the type definition file and convert PNotify to typed Svelte.

Hey @hperrin - just wanted to follow up on this? :)
