'TreeModule' does not appear to be an NgModule class

Issue

I just literally follow the step by step here in this documentation but for some reason im having this error when i try to import angular-tree-component in app.module.ts eror

i just follow the documentation written here https://angular2-tree.readme.io/docs/getting-started#slack-community.

Solution

Angular v16 has dropped the support for non-ivy libraries.

This library choose to not enable ivy by default.

So you won't be able to use it in a v16 project !
