在制作（Heroku）中，我收到以下错误：

我正在运行Rails 3.2.6，包括actionpack 3.2.6，我认为这个问题解决了这个问题：https://github.com/rails/rails/commit/6bb86e1f3f7f9e11ee1c056d8742125173ecbce1

我也试过这个："ActionView::Template::Error ( isn't precompiled)" raised on "image_tag nil"

基本上，只要此页面上的某个图像不存在，就会抛出此错误。如果我上传图片，它工作正常。有什么想法吗？

谢谢， --mark

我假设您正在使用像CarrierWave这样的东西来处理文件上传？您可以在上传器类中指定默认图像处理程序：

https://github.com/jnicklas/carrierwave#providing-a-default-url

class MyUploader < CarrierWave::Uploader::Base
  def default_url
    "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  end
end

这将输出默认图像，而不是尝试访问资产管道中名为“”的不存在的文件。
