angular-cli: You cannot use the new command inside an Angular CLI project.

Completely removing @angular/cli and reinstalling it seems to have done the trick.

@ASrima rm -r -f // might will probably delete a bunch of things that you don’t expect. It’s a bad idea to advise people to run this command.

@Ionaru can you check if you still have an angular-cli package installed globally? If you, please remove it.

And please verify if there is a mention of angular-cli in you package.json.
