You should use the 8.0.0 version of angular. But in yarn, I don't know why you are using angular 8.1.0.

hi, What's your Angular version? The original AspNet Zero uses v8.0. See https://github.com/aspnetzero/aspnet-zero-core/blob/dev/angular/yarn.lock#L177 If you delete yarn.lock it may update to v8.1, so restore it from the repository.

Please stay on Angular 8 until we find a way to solve this problem. I think this happens if you upgrade to Angular 8.1. if you install dependencies using yarn, it should work.

If you delete yarn.lock it may update to v8.1, so restore it from the repository.

@maliming

I haven't downgraded the project .. I just downgrade the Angular CLI to the 8.0.0. And you can see in the package JSON file its v8.0.0 is there. The error is not related to the version its shows that property has no to value so given error. you should troubleshoot that. :)

Thanks

You need to downgrade the angular related package in yarn.lock to 8.0 instead of angular cli.

@maliming thank you for the hint with downgrading to ng 8.0.x. It is working now for me. But this can't be the solution for the long run.

Could you please post into this thread once there is a solution for higher angular versions?
