Could you please provide your thought on this issue

Answer 1

You can't move compiled addons across different platforms like that (much like you can't copy a Linux executable to Windows and expect to be able to execute it). You will need to npm rebuild in your project directory to recompile any addons after you copy your project tree to a different platform.
