assets:precompile fails with “File exists” on Rails 3.2.15 with Asset Pipeline

问题

I am unable to precompile my assets for my Rails 3.2.15 asset pipeline enabled app.

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

These are the commands i run:

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

And i get the following error:

** 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

/usr/lib/ruby/gems/1.9.1/gems/activesupport-3.2.15/lib/active_support/core_ext/file/atomic.rb:36:in `atomic_write'

Only the latter file (which seems to change every time i run the command) is visible on disk, the former seems to be a temp file which is created and then moved. It is not visible after seeing the error.

Any ideas what on earth this means?

I am running Ubuntu 12.04.3 LTS, Rubygems 2.1.6, Bundler 1.3.5 and Ruby 1.9.3p429

Thanks
