It seems like you're using a project generated using an old version of the Angular CLI.
The latest CLI now uses webpack and has a lot of improvements including a simpler
workflow, a faster build, and smaller bundles.
To get more info, including a step-by-step guide to upgrade the CLI, follow this link:
