JQuery is working on development but not on Heroku

I can not get JQuery running when I deploy to Heroku, but everything works perfectly when you use localhost: 3000. I've tried running exec rake bundle assets: precompile This is my application file. js
This is my gemfile This is my development.rb file This is my production.rb file. I've tried to comment on the turbolinks but it still does not work. I looked at the Heroku logs but I do not see any mistakes either. I am always new to programming, so forgive me if I have forgotten something or if I have not followed a procedure. I read the Heroku documentation and tried to deploy again following their recommendations and JQuery remains without work. Any help in the right direction would be greatly appreciated.
It's there that you can find the deposit that I'm trying to deploy to Heroku.
