Hello @yangjunfocus,

I know this error, as I experienced it while implementing a new feature in the compiler. I fixed this scenario in @angular/compiler-cli 9.1.0 but you are still on 9.0.7. This results in an incompatibility between @angular/compiler at version 9.1.0.

Please upgrade @angular/compiler-cli to 9.1.0 to fix the problem.
