在我的 Rails 应用程序中，我有以下代码。
class ProjectImage < ApplicationRecord
belongs_to :project
has_many_attached :images do |attachable|
attachable.variant :thumb, resize_to_limit: [100, 100], saver: { quality: 80 }
attachable.variant :medium, resize_to_limit: [800, 800], saver: { quality: 75 }
end
end
在 gemfile 中
gem 'image_processing', '~> 1.2'
gem 'mini_magick'
我收到如下错误
/home/dinesh/.rvm/gems/[电子邮件受保护]_app/gems/image_processing-1.2.0/lib/image_processing/chainable.rb:15:在`saver'中：参数数量错误（给定1，预期 0) (参数错误)
在 Rails 控制台中尝试创建附加图像的缩略图和中等变体

图像处理gem的最新版本是1.13.0
1.2.0版本自6年前以来就没有更新过。
在 Gemfile 中更改此设置
gem "image_processing", "~> 1.0"
然后再次测试，如果可能的话，不要使用 Minimagick gem，因为问题似乎与此无关。
