How to add gem dependency to my ruby gem

Question

I think I am fundamentally missing something. I am learning ruby, and have been playing with Lita lately, and wrote(my first) a simple little gem to get some directions/distance from the bot. The problem I am having is where to put a gem dependency in my gem. To work, my gem requires the 'rest-client' gem. Where do I put this in my code so that it is available to my Directions class? Currently, to get it to run, I am requiring the gem in my bots actual gemfile. And when I bundle exec lita, it apparently becomes available for my gem to use... but if I remove it from there, I can't get it to work anywhere in my gem.. what am I missing? It is here if anyone wants to read the code and tell me where I should be adding it:

EDIT: I added the dependency like spickermann suggested. Then had to add require 'rest-client'to my directions.rb. Not entirely sure if this is the correct way, but it works now. Thanks for the help spickermann

lita-directions.gemspec下行放在您的lita-directions.gemspec旁边，该行旁边定义了对lita的依赖关系：

spec.add_runtime_dependency 'rest-client'
