Typescript version problem while updating Angular 8 to Angular 9
Angular 9 support typescript >=3.6 and <3.8. But while updating angular 8 to 9 the cli is installing ts 3.8 which is not supported by angular 9 itself.

Upgrading to version 9 requires very specific actions. The good news is they are all documented here.
https://github.com/angular/angular-cli/issues/17297
Summary
Upgrade to latest version of 8 first. Then to 9. Using the --force option fixes your issue.
