运行'rake资产：预编译'会产生错误：'`@ application.css'不允许作为实例变量名'

2012-07-14 59 views

我正在使用Rails 3.2应用程序，而且我试图测试预编译我的资产当我将我的应用程序投入生产时。该应用程序运行在发展很好，但是当我运行：运行'rake资产：预编译'会产生错误：'`@ application.css'不允许作为实例变量名'

bundle exec rake assets:precompile

我得到以下错误：

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

我搜索我的代码，并没有提及application.css，除了当然还有那个名字的文件（偶尔也有评论）。

我也尝试在生产模式下设置config.assets.compile = true，但也失败了（应用服务器启动正常，但在production.log中没有错误，我只看到请求，而Rails呈现响应，但不完成）。

感谢您的任何帮助。

这里有一个完整跟踪，当我运行bundle exec rake assets:precompile：

$ bundle exec rake assets:precompile --trace

编辑：

这里的config/environment.rb中：

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

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

而且这里的config /环境/生产。 rb：

个预订:: Application.configure在这里做指定 ＃设置将优先于配置/ 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 

    # Choose the compressors to use 
    config.assets.js_compressor = :uglifier 
    config.assets.css_compressor = :yui 

    # 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 

    # Defaults to Rails.root.join("public/assets") 
    # config.assets.manifest = YOUR_PATH 

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

编辑＃2：所以我config.assets.digest更改为false，现在rake assets:precompile运行正常，但是当我去启动服务器（nginx的+乘客PHUSION）我得到了相同的跟踪同样的错误： `@application.css' is not allowed as an instance variable name

编辑＃3：好吧，我已经缩小下来有点进一步。它肯定与public/assets/manifest.yml中的条目有关。我通过删除清单中的第一个条目（application.css）来测试此错误，并且错误更改以反映新的第一条目application.js。还是一样的错误，只是一个新的“实例变量”。
