Bug

https://github.com/angular/angular-cli/issues/14600

Solution 1:

It's a bug in Angular 8

you can work around it by using:

ng update @angular/cli @angular/core --allow-dirty

Solution 2:

I have tried using mention command for upgrading from angular 8 to angular 9, but was still getting the error.

Then i have tried same command with --force flag and it worked for me.

ng update @angular/cli @angular/core --allow-dirty --force
