I got the same error upgrading from angular 8 to 9. I had a tsconfig file in my project and it was linked well. In my case the error was caused by the @angular-devkit/schematics package. I resolved the error by the following steps:

  1. remove the package @angular-devkit/schematics from your package.json
  2. delete the node_modules and package-lock.json
  3. npm i (I need to execute npm i --legacy-peer-deps - but be careful with that)
  4. npx @angular/cli@9 update @angular/core@9 @angular/cli@9

Let me now if this worked. Hope this might help someone

When I was hit with this error. All I had to do was, run; 'ng update'. I was given the suggestion what to do next. Attached for reference below;

In my case I had to run as suggested; 'ng update @angular/core@12'

In order to run the migrations you need to install the @angular-devkit/core package

npm i @angular-devkit/core@<VERSION> -D
ng update --from <FROM_VERSION> --to <VERSION> --migrate-only --allow-dirty --verbose @angular/core

After migrations you could remove the package again.
