You need to update your Angular CLI. NOTE: the package has changed from angular-cli to angular/cli. Also check this link.
After you have updated your dependencies, your project probably won't work. Don't worry, you will find the answers somewhere on stackoverflow.
The version 4.6.1 is inside the project node_modules folder.
You are using an old version of angular cli, You should update to @angular/cli
npm uninstall -g angular-cli @angular/cli npm cache clean npm install -g @angular/cli For full instructions on the upgrade process you can view my answer here for upgrading angular-cli https://stackoverflow.com/a/41403927/5963307
