Rails 教程第 11 章。Carrierwave 和 Cloudinary。 Heroku 应用程序错误

Question

我正在学习 Rails 教程，但没有使用 AWS，因为我没有信用卡。

所以我尝试使用 Cloudinary。

我在这里完全是菜鸟，我什至不确定是否可以做到。 关键是我想在heroku上部署我的网站，我可以上传图片。

通过 localhost 可以正常工作，但在 heroku 上出现此错误：

No command 'run' found, did you mean:

我的图片上传器.rb

# encoding: utf-8

class PictureUploader < CarrierWave::Uploader::Base

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

   include CarrierWave::MiniMagick
   process resize_to_limit: [400, 400]
  include Cloudinary::CarrierWave


   # process :tags => ['post_picture']

#   version :standard do
#    process :resize_to_fill => [200, 300, :north]
#  end

#  version :thumbnail do
#    resize_to_fit(50,50)
#  end

#  def public_id
#    return model.short_name
#  end

  # Choose what kind of storage to use for this uploader:
  if Rails.env.production?
    #storage :cloudinary
     storage :fog
  else
    storage :file
  end


  # 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

  # 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 files as they are uploaded:
  # process :scale => [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process :resize_to_fit => [50, 50]
  # 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

  # 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

end

通过本地主机，它工作正常。

在 heroku 上，它根本不显示。
