Rails 3.1.1资产预编译 - rake中止

ruby-on-railsruby-on-rails-3.1precompileasset-pipeline
10

编辑：还有人有什么建议吗？我完全被卡住了！！！

我有一个应用程序，其中所有资源都可以编译正常，但在这个第二个应用程序中，当我运行：

RAILS_ENV=production rake assets:precompile --trace

我收到了以下消息：undefined method `directory?' for nil:NilClass

请帮忙解决。当我查看public/assets目录时，发现图像文件已经预编译，但是没有js或css文件。

以下是完整的终端输出:

我猜测你在配置方面出了问题，可能是路径输错了之类的。我会执行 bundle open sprockets 命令并添加一些调试输出来查看是哪个路径引起了错误。 - phoet
你能给我一个例子，如何在Sprockets中进行调试吗？ - allesklar

你可以使用bundle open sprockets命令，然后使用你最喜欢的文本编辑器添加puts语句、调试代码或者pry调试工具等，以满足你的需求。 - phoet
你一定是个非常优秀的程序员。我很愿意学习，但我不确定在哪里放置语句。在sprockets中有很多文件和大量代码，我无法确定在哪里放置puts语句以及确切要输出什么。你能给我更多的指导吗？ - allesklar
没关系，我意识到跟踪指向了base.rb的第122行。傻瓜 - allesklar

感谢phoet：我刚在.bundle/ruby/1.9.1/gems/sprockets-2.0.2/lib/sprockets/base.rb中加入了begin..rescue块，错误是由于一个无效的符号链接引起的（仅在Rails 3.1.1 Sprockets 2.0.2的生产环境中，另外Rack 1.3.4会导致constant WFKV_警告，但Rack 1.3.3则不会）。

120  paths << path
121  begin
122    if stat(path).directory?
123      each_entry(path) do |subpath|
124        paths << subpath
125      end
126    end
127  rescue
128    puts "error with directory #{path}"
129  end

现在错误已经消失了，bundle exec rake assets:precompile --trace执行结束，但是在最后两个步骤** Execute assets:precompile:primary之后需要等待很长时间...我们拭目以待 ;)

这里的关键词是“损坏的符号链接”。 - givanse

感谢Phoet的建议，我在sprockets的基本文件中添加了一个puts语句，从而找出了罪魁祸首文件。这是一个ckeditor js文件。我已经将ckeditor移出管道，在公共目录中，但这个文件还是被调用了。我仍然不知道为什么。但是我在assets/javascripts目录中放置了一个虚拟的ckeditor.js文件，就足以解决我的问题。
