@Abiy follow your step in email:

You can fix this by editing the index html, find the line that includes systemjs.config.server.js and edit it to include systemjs.config.js instead.
The systemjs.config.js is already configured to include packages from local directory.
I hope this helps.
The issue is caused by a missing npm package , you can also try changing the version of the package

it works ,thanks a lot
