UPDATE:
this error is shown during git push heroku master
:
-----> Preparing app for Rails asset pipeline
Running: rake assets
Solved.
Simply by comment out the following line in Gemfile :
#gem 'twitter-bootstrap-rails', :git => 'http://github.com/seyhunak/twitter-bootstrap-rails.git'
and using gem "twitter-bootstrap-rails", "~> 2.0.1.0"
then running bundle update
To be complete, my previous failing branch was :
- revision: a5d67d23afeaa76eb52c6f87d55ff407f9c753f2
- twitter-bootstrap-rails (2.0.1)
