Error npm building grapesjs plugin - resolved

hey can someone tell me how to build grapesjsbuilder? I am trying to make a email compatible video block but im stuck on:

 [~/flow.numinousonline.com/plugins/GrapesJsBuilderBundle]# npm run build

Is grapesjs/dist/css/grapes.min.css supposed to exist? Im sorry if this is a newbie question as I have not worked with npm as much as others.

Any help would be appreciated.

Needed to run npm run build first i guess. Seem to have gotten past that. Now on to coding.
