I’ve been working on deploying my first rails app to heroku for the past few nights and am struggling to figure out how to solve this problem.
I used Michael Hartl’s tutorial (http://ruby.railstutorial.org/chapters/beginning#sec-deploying) to make sure I set up my app on the Cedar Stack.
Per the Heroku tutorial, I’m using “thin” as the server.
I’ve read a bunch of posts and have precompiled my assets using:
heroku run bundle exec rake assets:precompile
bundle exec rake assets:precompile
I have also migrated my databases.
My app works on my localhost.
Here is my gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.8'
gem 'bootstrap-sass', '2.0.0'
gem 'bcrypt-ruby'
gem 'thin'
group :development, :test do
gem 'rspec-rails'
end
group :development do
gem 'sqlite3'
end
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :production do
gem 'pg'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
group :test do
gem 'capybara'
gem 'factory_girl_rails'
end
Here are my heroku logs

Here’s how I ultimately solved the problem(s). Thanks to the folks who referred me elsewhere so that I could put it all together.
First, I moved Blueprint to a vender directory. I don’t think that’s crucial to the solution, but it felt cleaner.
The compilation problem:
This thread: blueprint css rails 3.1 help was really helpful. I found Martin and Gary’s responses (nos 2 and 3) more helpful than the selected response.
Part of why I was having trouble with compilation (personally) is because I made some edits to the Blueprint files, which meant that they needed to be compiled again before deployment.
This thread: rails 3.1.0 ActionView::Template::Error (application.css isn't precompiled) was helpful in that regard. Basically, just run “Bundle exec rake assets:precompile” before uploading to heroku. I also run “heroku run rake assets:precompile” after upload.
How I got rid of the URL slashes in my links:
The URLs are the result of this code in Blueprint/print.css:
I solved the problem by commenting out that code. Of course, after changing the file, you have to rake assets:precompile again. But, that got it all working!
