Other details that might be useful

I have used npm to uninstall @angular/cli and reinstall it globally. Other commands also fail with the same error. For example ng g component some-new-component also throws the error:

The command "generate" has an option without the required type and name fields.

Just spoke with @hansl - he reverted the last commit to https://github.com/angular/devkit. I just tested after reinstalling the CLI and everything is back to working.
