Angular 8 ng build --prod gives Error during template compile of 'Injectable'

I upgraded from angular 6 to 8 and updated all the libraries used in the project. Everything seems to be running fine but when I use ng build --prod, I get these errors

I already searched for solutions and got things like changing absolute path to relative. I did that still I get these issues

Answer 1

Adding this to tsconfig.json worked for me

"compilerOptions": {
    "paths": {
        "@angular/*": [ "node_modules/@angular/*"]
    }
  }

There is a regression (a behavior that used to work and stopped working in a new release) open ticket for this issue. And under that issue there is the solution: https://github.com/angular/angular/issues/23609#issuecomment-386876693
