運行'rake資產：預編譯'會產生錯誤：'`@ application.css'不允許作爲實例變量名'

我正在使用Rails 3.2應用程序，而且我試圖測試預編譯我的資產當我將我的應用程序投入生產時。該應用程序運行在發展很好，但是當我運行：運行'rake資產：預編譯'會產生錯誤：'`@ application.css'不允許作爲實例變量名'

bundle exec rake assets:precompile

我得到以下錯誤：

rake aborted! 
`@application.css' is not allowed as an instance variable name

我搜索我的代碼，並沒有提及application.css，除了當然還有那個名字的文件（偶爾也有評論）。

我也嘗試在生產模式下設置config.assets.compile = true，但也失敗了（應用服務器啓動正常，但在production.log中沒有錯誤，我只看到請求，而Rails呈現響應，但不完成）。

感謝您的任何幫助。

這裏有一個完整跟蹤，當我運行bundle exec rake assets:precompile：

$ bundle exec rake assets:precompile --trace 
** Invoke assets:precompile (first_time) 
** Execute assets:precompile 
/Users/alb64/.rbenv/versions/1.9.2-p320/bin/ruby /Users/alb64/.rbenv/versions/1.9.2-p320/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace

編輯：

這裏的config/environment.rb中：

# Load the rails application 
require File.expand_path('../application', __FILE__) 
require 'rails_extensions' 

# Initialize the rails application 
Reservations::Application.initialize!

而且這裏的config /環境/生產。 rb：

個預訂:: Application.configure在這裏做指定 ＃設置將優先於配置/ application.rb中

# The production environment is meant for finished, "live" apps. 
    # Code is not reloaded between requests 
    config.cache_classes = true 

    # Full error reports are disabled and caching is turned on 
    config.consider_all_requests_local  = false 
    config.action_controller.perform_caching = true 

    # Specifies the header that your server uses for sending files 
    config.action_dispatch.x_sendfile_header = "X-Sendfile" 

    # For nginx: 
    # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' 

    # If you have no front-end server that supports something like X-Sendfile, 
    # just comment this out and Rails will serve the files 

    # See everything in the log (default is :info) 
    # config.log_level = :debug 

    # Use a different logger for distributed setups 
    # config.logger = SyslogLogger.new 

    # Use a different cache store in production 
    # config.cache_store = :mem_cache_store 

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

    # Enable serving of images, stylesheets, and javascripts from an asset server 
    # config.action_controller.asset_host = "http://assets.example.com" 

    # Disable delivery errors, bad email addresses will be ignored 
    # config.action_mailer.raise_delivery_errors = false 

    # Enable threaded mode 
    # config.threadsafe! 

    # Enable locale fallbacks for I18n (makes lookups for any locale fall back to 
    # the I18n.default_locale when a translation can not be found) 
    config.i18n.fallbacks = true 

    # Send deprecation notices to registered listeners 
    config.active_support.deprecation = :notify 

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

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

編輯＃2：所以我config.assets.digest更改爲false，現在rake assets:precompile運行正常，但是當我去啓動服務器（nginx的+乘客PHUSION）我得到了相同的跟蹤同樣的錯誤： `@application.css' is not allowed as an instance variable name

編輯＃3：好吧，我已經縮小下來有點進一步。它肯定與public/assets/manifest.yml中的條目有關。我通過刪除清單中的第一個條目（application.css）來測試此錯誤，並且錯誤更改以反映新的第一條目application.js。還是一樣的錯誤，只是一個新的「實例變量」。

這可能不是您的application.css文件的錯。問題是與迷幻，可能是因爲它是導致加載公共/資產/ manifest.yml問題，看到這個類似的錯誤在編織提交，可能的解決：

嘗試刪除鬥志，或者如果那是不可能的，在那裏尋找問題。請參閱您的堆棧跟蹤的這一部分：

psych.rb:205:in `load_file'

你應該能夠找到一個補丁鬥志，如果你想保持它西港島線解決這個問題。

謝謝你，你是正確的。目前，我已經用syck取代了psych。 – fuzzybassoon 2012-11-01 19:44:05
