Rails 4 Heroku assets:precompile error - ruby-on-rails

I am trying to create a Rails app in Heroku. I run it locally(nitrous.io) and works fine. I am not sure what is going on here and no idea what I did wrong. I have already read many other answers on SO but none seemed to work for me. I hope someone has experience with this and can help me out!
Following the directions here I already added this:
#config/application.rb
config.serve_static_assets = true
#Gemfile
gem 'rails_12factor', group: :production
.
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile

! Precompiling assets failed.
!
! Push rejected, failed to compile Ruby app
I found out what the problem was. I had placed gems used in the application under development and test in the Gemfile. This resulted in that the Gems were not included in the deployment. I got the same error for bootstrap, so next time I will be sure to add gems outside the dev and test clause.
Thanks for the help though :)
I think you have not pushed your updated Gemfile and Gemfile.lock on heroku.

heroku push error: "rake assets:precompile rake aborted!"

I'm trying to push my changes to Heroku with the following command: git push heroku master
When running the rake assets:precompile, I get the following error(s):

Appreciate any help. First time learning RoR.
What's inside the file config/environments/production.rb at line 80?
Search your code, specifically in the production.rb file. It's likely there is a fkalkhalidi string somewhere that is causing the error.

I get similar errors when I try to run rails server or rails console. Would really appreciate any help!! Thanks a lot!
Usually rails apps have config/database.yml.example, copy this file to config/database.yml and overwrite database connection settings if necessary.

Heroku Precompiled Assets Failed

I am having difficulties troubleshooting the following and figuring out why my assets are failing to precompile at slug compilation... the odd thing is, is that the assets compile fine at runtime when I check the live logs... any ideas? Is it trying to connect to the database?

Check whether your asset precompile requires access to ENV variables during when its run. Its hard to tell from your stack trace, but this might be a good resource to check out: https://devcenter.heroku.com/articles/rails-asset-pipeline
Essentially, you can enable the user-env-compile labs feature on heroku to give your app instance access to ENV vars during your precompile.
heroku labs:enable user-env-compile -a myapp
more information about that here: https://devcenter.heroku.com/articles/labs-user-env-compile
I had just added Unicorn, I added the following to my application.rb in config and was able to precompile:
config.assets.initialize_on_precompile = false
