我正在使用 Rails 3.1 RC 和 Carrierwave 0.5.4。不知道是不是3.1的问题。

我验证了我的 S3 存储桶中存在路径和文件 (http://bucket_name.s3.amazonaws.com/unencoded/users/1/photos/test.gif)。

当我做：

Photo.first.update_attributes!(:job_state => 'processing', :remote_attachment_url => 'http://bucket_name.s3.amazonaws.com/unencoded/users/1/photos/test.gif')

我得到的错误：

Errno::ENOENT: No such file or directory - /Users/Chris/Sites/site_name/tmp/uploads/20110603-1813-612-6936/small_test.gif

为什么 Carrierwave 尝试访问本地目录而不是 S3？

我的初始化程序看起来像：

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',       # required
    :aws_access_key_id      => APP_CONFIG['amazon_access_key_id'],       # required
    :aws_secret_access_key  => APP_CONFIG['amazon_secret_access_key']       # required
  }
  config.fog_directory  = 'bucket_name'                     # required
  config.fog_host       = 'http://cdn.site_name.com'            # optional, defaults to nil
  config.fog_public     = true                                   # optional, defaults to true
  config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}  # optional, defaults to {}
end

我的上传器类看起来像：

# encoding: utf-8

class PhotoUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/users/#{model.user.id}/#{model.class.to_s.underscore}s/#{model.id}"
  end

  # Create different versions of your uploaded files:
  version :small do
    process :resize_to_fill => [53,53]
  end
  version :medium do
    process :resize_to_fill => [106,106]
  end
  version :large do
    process :resize_to_fill => [212,212]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_white_list
    %w(jpg jpeg gif png)
  end

  # https://github.com/jnicklas/carrierwave/wiki
  # Heroku has a read-only filesystem, so uploads must be stored on S3 and cannot be cached in the public 
  # directory. You can work around the caching limitation by setting the cache_dir in your Uploader classes 
  # to the tmp directory.
  def cache_dir
    "#{Rails.root}/tmp/uploads"
  end
end

在我的上传器类中，如果我删除版本，上传成功且没有任何错误。

有人遇到同样的问题吗？

嗯，我不知道到底是什么问题，但我从以下位置切换了我的 gem 文件：

gem 'carrierwave', :git => 'http://github.com/jnicklas/carrierwave.git'

到

gem 'carrierwave', '0.5.4'

问题似乎已经消失了。主版肯定有问题...

希望这对在 Rails 3.1 RC 和 Carrierwave 上遇到相同问题的人有所帮助。

这是你的代码

  def cache_dir
    "#{Rails.root}/tmp/uploads"
  end

您的应用程序正在使用它来处理图像。

以下命令应该可以解决问题。在 Ubuntu 上是这样的：

sudo apt-get install imagemagick
