Navigating through the Angular Upgrade Roadmap: Transitioning from 5.0 to 6

As per the instructions found in this helpful guide, I executed 

rxjs-5-to-6-migrate -p src/tsconfig.app.json

Please note: I have already deleted the node_modules folder and reinstalled with npm i, but the error persists.
