Answer 1

You use a custom package registry which requires an active certificate.

It is not project or Angular related, it's npm and registry related.

Your options are:

1. Renew your certificate
2. Use a different or default registry
3. Make it so that your registry no longer requires a certificate.

Check npm config list to see your current settings
