>SOLUTION

If using angular-cli, do:

npm uninstall -g angular-cli
npm install -g @angular/cli

If desired to perform just local changes, take out the "-g" option.

Sometimes, when a project is recently created using deprecated packages, it is faster to recreate the project using the new env, up to date.
