@pptyasar the @circlon/angular-tree-component package is not compatible with Angular 7. You should try and use the angular-tree-component package, probably with version 7.2.1. Please note that we focus the development on Angular 9 and up.

I believed this @tobiasengelhardt

@pptyasar Sorry for the confusion, I mixed up the version numbers. But you still can not use the @circlon/angular-tree-component package with Angular 7. We are working on a new documentation that will make this clearer.

Use angular-tree-component in version 8.5.6 with Angular 7. Tested this myself and there are no errors with ng serve. Please note that the installation is slightly different because it's a different package:

Use this import in your css: @import '~angular-tree-component/dist/angular-tree-component.css'; Use this import in your app module: TreeModule.forRoot()

When you update your app to Angular 8 you can continue using the tree like that. When you are at Angular 9 or higher you should switch to the @circlon/angular-tree-component package. The imports are different and the migration path is described in the changelog.
