I created a jekyll theme nepaliBabu, I successfully built the gemspec and installed locally on my device

but however when I use it on my jekyll site Gemfile like this:

gem "nepaliBabu", path: "C:/Users/super/Desktop/LoftyInc/nepaliBabu"

and in _config.yml mentioning theme as nepaliBabu but whenever I try to serve it locally i get this error saying, nepalibabu isn't found.
