i new ruby , have been stuck on bug quite time. don't think have syntax errors in file trying load. help appreciated.

where file located you're running from? root?

if you, can do:

require_relative 'lib/guide'

for me, i'm requiring outside files spec director, calls this:

require_relative '../lib/guide'

ruby require
