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.

enio created 4 years ago

@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?

hi @ravindrapatail

Can you check the version of the angular related package in your yarn.lock file?

Make sure they @^8.0.0

https://github.com/aspnetzero/aspnet-zero-core/blob/dev/angular/yarn.lock#L114

enio created 3 years ago

My understanding of the ^8.0.0 pattern is that npm/yarn will install the latest version with 8.x.x. Therefore in my scenario the problem suddenly occured when angular has published version 8.1. So my build automatically switched to 8.1. My solution was simple - I have just changed all angular related entries in package.json from ^8.0.0 to ~8.0.0. In my opinion this pattern represents 8.0.x - therefore the angular version was nailed down to 8.0 and not switching to the problematic 8.1 version.

expiriencing the same issue after 7.1 upgrade (yarn + core + angular)

joe704la created 3 years ago

I followed enio suggestion of switching all angular packages from ^8.0.0 to ~8.0.0. This works as a temporary solution. But it for sure seems to be an issue with angular 8.1.

hi all

Please use angular less than or equal to v8.0.0. Please follow this Github issue: https://github.com/aspnetzero/aspnet-zero-core/issues/2476

Angular has fixed the above problem, but has not released a new version, let us wait
