@Tileset = Gosu::TexturePacker.load_json(
self, media_path('ground.json'), :precise
)

I removed :precise and ran the code
@Tileset = Gosu::TexturePacker.load_json(
self, media_path('ground.json')
)
and it is giving the err

The book was written around 7 years ago, gosu was updated, but book was not. Also https://github.com/spajus/gosu-texture-packer was updated. Unfortunately I no longer support or update the book or the code samples, so the best you can do is figure out what versions of gosu and gosu_texture_packer you are using, get their source code, and figure out how to fix it. Changes should be pretty minimal.
