Ruby on rails 资产：预编译失败，返回“0”；“文件存在”；在Rails 3.2.15上使用资产管道

我无法为启用Rails 3.2.15资产管道的应用程序预编译我的资产

Gemfile:

# Asset pipeline
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier',     '1.3.0'
end

production.rb

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = false

  # Compress JavaScripts and CSS
  config.assets.compress = true

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = false

  # Generate digests for assets URLs
  config.assets.digest = true

  # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
  config.assets.precompile += %w( *.js *.css )

  # Choose which compressors to use
  # config.assets.js_compressor  = :uglifier
  # config.assets.css_compressor = :scss

以下是我运行的命令：

bundle exec rake assets:clean RAILS_ENV=production --trace
bundle exec rake assets:precompile RAILS_ENV=production --trace

我得到以下错误：

** Invoke assets:precompile (first_time)
** Execute assets:precompile
/usr/bin/ruby1.9.1 /usr/local/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace

** Execute assets:precompile:all
** Invoke assets:precompile:primary (first_time)
** Invoke assets:environment (first_time)

** Execute environment
** Invoke tmp:cache:clear (first_time)
** Execute tmp:cache:clear
** Execute assets:precompile:primary

磁盘上只有后一个文件（每次运行命令时似乎都会更改）可见，前一个文件似乎是一个临时文件，创建后再移动。它在看到错误后不可见

你知道这到底是什么意思吗

我正在运行Ubuntu12.04.3LTS、Rubygems 2.1.6、Bundler 1.3.5和Ruby 1.9.3p429

谢谢

您可以手动删除

tmp

内容

rm-rf tmp/*

？，然后再次预编译，有帮助吗？这似乎奏效了？！在尝试预编译之前，我还运行了

rm-rfpublic/assets/

，以获得良好的度量。。。我还不想接受这个答案，因为它看起来不令人满意，但我会在接下来的几天里测试并回来。谢谢你的帮助！有什么最新消息吗？我在Chef deploy/before_migrate.rb脚本中遇到了类似的问题，需要一个干净的解决方案。

rake assets:clobber

可能会有所帮助。不确定。上面的诺恩正在为我们解决这个神秘的问题：/
