我试图将我的应用程序部署到Heroku。我正在使用Rails 4，最新的Devise（都在仓库中尝试过3.0.0.rc）和ruby 1.9.3（也尝试过2.0）。我无法克服最初的推动力，好像heroku没想到设计。本地assets:precompile任务运行没有问题。这是输出：
git push heroku master -----> Ruby/Rails app detected

Your bundle is complete! It was installed into ./vendor/bundle
Post-install message from haml:
HEADS UP! Haml 4.0 has many improvements, but also has changes that may break
your application:
* Support for Ruby 1.8.6 dropped
* Support for Rails 2 dropped
* Sass filter now always outputs <style> tags
* Data attributes are now hyphenated, not underscored
* html2haml utility moved to the html2haml gem
* Textile and Maruku filters moved to the haml-contrib gem
For more info see:
http://rubydoc.info/github/haml/haml/file/CHANGELOG.md
Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:
<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
Post-install message from twitter-bootstrap-rails:
Important: You may need to add a javascript runtime to your Gemfile in order for bootstrap's LESS files to compile to CSS.
