React-css-themr worked perfectly locally but not worked when used it after publishing it and used it as component lib into other project

I used react-css-themr to implement delicious theme into my component(e.g. button) so for component project it works fine (like priority is ---> external theme 1st and if not getting external theme(button.scss from delicious theme folder) it use internal theme (button.scss from component's scss folder)).

this is working fine for this project. but if i deploy this project and use as library into other project (like button component to my main project)then it always loaded default css instead of external css.
can any one please help me in this?

Reproduce the published button component in the consuming project, comparing the external button.scss from the delicious theme folder with the internal button.scss in the component project. Start by tracing how react-css-themr resolves those two themes after publication; done means the consuming project loads the external theme instead of the default CSS.
