npm run build:prod error

Running the demo project cloned from git.

Failing to build:prod

suspect the error is in @nebular/theme 2.0.0-rc.9

ERROR in : 'nb-card-header' is not a known element:

1. If 'nb-card-header' is an Angular component, then verify that it is part of this module.
2. If 'nb-card-header' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. (" [ERROR ->] {{cardheader}} ")
