我在Digital Ocean Centos Nginx盒子上运行Rails 4.1.2应用程序。
我试图让carrierwave背景资料在后台存储图像，但是每次执行作业时我都会收到以下错误：

奇怪的是，错误顶行报告的图像确实存在。它似乎不是一个权限的东西，因为我已经尝试将其设置为777进行实验。
如果没有载波背景，图像处理工作正常，则会上传所有内容并创建正确的版本。
我在这里遗漏了什么或者误解了设置？
我目前的代码如下：
# encoding: utf-8
class ItemImageUploader < CarrierWave::Uploader::Base
include ::CarrierWave::Backgrounder::Delay
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
include CarrierWave::MiniMagick
# include CarrierWave::ImageOptimizer
def store_dir
"#{Rails.root}/public/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Create different versions of your uploaded files:
version :thumb do
process :resize_to_limit => [50, 50]
end
version :gallery do
process :resize_to_limit => [300, 300]
end
version :large_image do
process :resize_to_limit => [700, 400]
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
end
carrierwave.rb
# config/initializers/carrierwave.rb
CarrierWave.configure do |config|
config.fog_credentials = {
# Configuration for Amazon S3 should be made available through an Environment variable.
# For local installations, export the env variable through the shell OR
# if using Passenger, set an Apache environment variable.
#
# In Heroku, follow http://devcenter.heroku.com/articles/config-vars
#
# $ heroku config:add S3_KEY=your_s3_access_key S3_SECRET=your_s3_secret S3_REGION=eu-west-1 S3_ASSET_URL=http://assets.example.com/ S3_BUCKET_NAME=s3_bucket/folder
# Configuration for Amazon S3
:provider => 'AWS',
:aws_access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:aws_secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'],
:region => ENV['AWS_REGION']
}
config.enable_processing = false
# For testing, upload files to local `tmp` folder.
if Rails.env.test? || Rails.env.cucumber?
config.storage = :file
config.enable_processing = false
config.root = "#{Rails.root}/tmp"
elsif Rails.env.development?
config.storage = :file
else
# config.storage = :fog
config.storage = :file
end
# config.cache_dir = "#{Rails.root}/tmp/uploads" # To let CarrierWave work on heroku
config.fog_directory = ENV['S3_BUCKET_NAME']
end
item.rb的
class Item < ActiveRecord::Base
require 'acts-as-taggable-on'
acts_as_taggable
acts_as_taggable_on :location
belongs_to :user
has_many :categories
has_many :extra_item_images
validates :title, :price, :description, presence: true
mount_uploader :main_image, ItemImageUploader
store_in_background :main_image
# process_in_background :main_image
accepts_nested_attributes_for :extra_item_images
end
我完全迷失了，一直让我走了几天，并在谷歌上尽我所能，所以任何帮助都会非常感激。
