.svg上传不适用于carrierwave和rmagick

Question

我正在使用载波和rmagick来处理图像上传。但是在上传.svg格式文件时遇到了一个问题。

Failed to manipulate with rmagick, maybe it is not an image?

这就是我的上传器外观

class ClientImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :file
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
  process :resize_to_fit => [200, 200]
  version :thumb do
    process resize_to_fit: [320, 320]
  end
  def extension_whitelist
    %w(jpg jpeg gif png svg)
  end
end

我调查了一下并进行了更改，但仍然显示相同的错误。 carrierwave png thumbnails from svg upload

我所做的更改是

version :thumb do
  def full_filename(for_file)
    super(for_file).chomp(File.extname(super(for_file))) + '.png'
  end
  process resize_to_fit: [320, 320]
end

知道我要去哪里了吗
