通过twitter-bootstrap-rails gem升级到bootstrap 2.0.1后，Heroku部署失败
更新：
在git push heroku master显示此错误：
-----> Preparing app for Rails asset pipeline Running: rake assets:precompile rake aborted! couldn't find file 'twitter/bootstrap' (in /tmp/build_2pmsvze33th3e/app/assets/javascripts/application.js:9) Tasks: TOP => assets:precompile:primary (See full trace by running task with --trace) Precompiling assets failed, enabling runtime asset compilation Injecting rails31_enable_runtime_asset_compilation Please see this article for troubleshooting help: http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting
我按照本指南将Bootstrap 2布局升级到2.0.1。 之后，我将这个错误发送到了Heroku：

以前我有一个已经在Heroku Cedar上使用Bootstrap 2布局的现有Rails 3.1.3应用程序。
任何的想法 ？
删除以下文件app / assets / stylesheets / bootstrap.css.less并享受。 Soruce https://github.com/seyhunak/twitter-bootstrap-rails/issues/123
我还在资产组之外移动了gem“twitter-bootstrap-rails”，这有效！
我能够通过简单地将gem“twitter-bootstrap-rails”移出：assets块并将其置于我的gemfile顶部来解决这个问题。
解决了。
只需在Gemfile中注释掉以下行：
#gem 'twitter-bootstrap-rails', :git => 'http://github.com/seyhunak/twitter-bootstrap-rails.git'
并使用gem "twitter-bootstrap-rails", "~> 2.0.1.0"然后运行bundle update
要完成，我之前失败的分支是：
- revision: a5d67d23afeaa76eb52c6f87d55ff407f9c753f2 - twitter-bootstrap-rails (2.0.1)
对我来说，解决方案是在application.css中删除这一行
*= require twitter/bootstrap

运行时资产编译期间出现错误的另一种解决方法是使用asset_sync gem。
