Deploy Rails App on Heroku - Precompile Asset Errors

I use bootstrap on rails app, precompile appear when i deploy rails app on heroku. (Rails 4)

I resolved and worked

I added bootstrap to Gemfile

gem 'bootstrap-sass', '3.2.0.0'

Run command

# bundle install

My styles.css

@import "bootstrap-sprockets";
@import "bootstrap";

I changed file name to styles.css.scss

Reupload rails app to github and push to heroku app. That error resolved.

May be use!

# git push heroku master -f

Edit following line if bootstrap not work on heroku

# config/environments/production.rb
config.assets.compile = true

Then reupload to github and heroku.
