Assistance Needed with npm run build Build Errors during SageMathCell Server Installation

[Elimboto Yohana]

Dear SageMathCell Community,

I am currently working on installing SageCell on my Ubuntu VPS and have encountered several errors during the npm run build process after executing the command: ../sage/sage -sh -c make.

I also attempted to resolve the issues by using the command: ../sage/sage -sh -c make -B but I continue to face these errors regarding missing JavaScript modules:

ERROR in ./js/interact_cell.js

webpack 5.94.0 compiled with 6 errors in 42713 ms
make: *** [Makefile:42: static/embedded_sagecell.js] Error 1

Could you please provide guidance on how to address these errors? Any insights or suggestions would be greatly appreciated.

Kind regards,
