我正在开发一个 Rails 3.2 应用程序,并且我正在尝试测试预编译我的资产,以便将我的应用程序投入生产。该应用程序在开发中运行良好,但是当我运行时:

bundle exec rake assets:precompile

我收到以下错误:

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

我搜索了我的代码,没有引用 application.css,当然除了那个名称的文件(以及偶尔的评论)。

我也尝试过config.assets.compile = true在生产模式下设置,但同样失败(应用服务器启动正常,但在 production.log 中没有错误,我只看到请求,Rails 呈现响应,但没有完成) .

谢谢你的帮助。

这是我运行时的完整跟踪bundle exec rake assets:precompile

编辑:

这是 config/environment.rb:

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

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

这是 config/environments/production.rb:

Reservations::Application.configure do # 此处指定的设置将优先于 config/application.rb 中的设置

  # 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:所以我已将 config.assets.digest 更改为 false,现在rake assets:precompile运行良好,但是当我启动服务器(nginx + 乘客 phusion)时,我得到了相同的错误和相同的跟踪: `@application.css' is not allowed as an instance variable name

编辑#3:好的,我已经进一步缩小了范围。它肯定与 public/assets/manifest.yml 中的条目有关。我通过删除清单 (application.css) 中的第一个条目来测试这一点,并且错误更改以反映的第一个条目application.js。仍然是同样的错误,只是使用了一个新的“实例变量”。

这可能不是您的 application.css 文件的错。问题出在 psych 上,可能是因为它导致加载 public/assets/manifest.yml 时出现问题,在 braid 提交上看到这个类似的错误,并有一个可能的解决方案:

https://github.com/evilchelu/braid/commit/f08fac25570a1a56de8d6282f637d0604ef5e210

尝试删除心理,或者如果这不可能,则在那里寻找问题。查看堆栈跟踪的这一部分:

 psych.rb:205:in `load_file'

如果您想保留它,您应该能够找到一个可以解决此问题的 psych 补丁。
