Aws :: S3 :: Errors :: NoSuchKey：指定的密钥不存在

Question

我正在使用gems carrierwave和carrierwave-aws。 我尝试S3

namespace :avatar do 
    desc 'Regenerate all user avatars' 
    task regenerate_avatars: :environment do 
    Bar.find_each do |bar| 
     bar.profile_picture.recreate_versions! if bar.profile_picture? 
     bar.save! 
    end 
    end 
end 

创建将图像调整rake任务，但我得到错误的AWS :: S3 ::错误:: NoSuchKey：指定的键不存在。

文件carrierwave.rb

CarrierWave.configure do |config| 
    config.storage = :aws 
    # for bucket name 
    config.aws_bucket = Rails.application.secrets.aws_bucket_name 
    config.aws_acl = "public-read-write" 
    config.aws_authenticated_url_expiration = 60 * 60 * 24 * 7 

    config.aws_credentials = { 
    access_key_id:  Rails.application.secrets.aws_access_key_id, 
    secret_access_key: Rails.application.secrets.aws_secret_access_key, 
    region:   Rails.application.secrets.aws_region 
    } 
end 

在文件上传

# encoding: utf-8 

class BarPictureUploader < CarrierWave::Uploader::Base 

    # Include RMagick or MiniMagick support: 
    # include CarrierWave::RMagick 
    include CarrierWave::MiniMagick 

    # Choose what kind of storage to use for this uploader: 
    # Aws storage for images 
    storage :aws 
    # 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/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" 
    end 

    def cache_dir 
    Rails.env.test? ? "#{Rails.root}/tmp/spec/uploads/tmp/uploads" : "#{Rails.root}/tmp/uploads" 
    end 

    # Provide a default URL as a default if there hasn't been a file uploaded: 
    # def default_url 
    # # For Rails 3.1+ asset pipeline compatibility: 
    # # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_')) 
    # 
    # "/images/fallback/" + [version_name, "default.png"].compact.join('_') 
    # end 
    process :resize_to_fit => [1024, 768] 
    version :bar_detail do 
    process :resize_to_fit => [200, 200] 
    end 

    version :bar_index do 
    process :resize_to_fit => [80, 70] 
    end 

    # def recreate_all_versions 
    # Bar.find_each do |bar| 
    #  bar.profile_picture.recreate_versions! if bar.profile_picture? 
    #  bar.save! 

    # 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 JPG JPEG GIF PNG) 
    end 

    # Override the filename of the uploaded files: 
    # Avoid using model.id or version_name here, see uploader/store.rb for details. 
    # def filename 
    # "something.jpg" if original_filename 
    # end
