ruby-on-rails – Paperclip错误 – NotIdentifiedByImageMagickError

我正在尝试用回形针将图像上传到aws s3,但是我收到了这个错误

Command :: file -b --mime '/var/folders/d_/k4_ps9hj5fj_3df5t210vjym0000gn/T/2611a2396a4af6938e5c5867c8bb409f20140515-7787-1u773ft.jpg'
Command :: identify -format '%wx%h,%[exif:orientation]' '/var/folders/d_/k4_ps9hj5fj_3df5t210vjym0000gn/T/2611a2396a4af6938e5c5867c8bb409f20140515-7787-1rep3kt.jpg[0]' 2>/dev/null

在我的模型中,我设置了这些样式

has_attached_file :photo,:storage => :s3,:s3_credentials => "#{Rails.root}/config/s3.yml",:path => "/:style/:id/:filename",:styles => { :medium => "300x300>",:thumb => "100x100>" },:default_url => "/assets/profile/iama.png"

当我删除这些样式时,一切正常,但我真的需要它们.

我正在使用Rails 3.2.16和

paperclip (4.1.1)
      activemodel (>= 3.0.0)
      activesupport (>= 3.0.0)
      cocaine (~> 0.5.3)
      mime-types

我已经安装了ImageMagick和rmagick gem

请帮帮我.

解决方法

问题是我的ImageMagick没有JPEG代表.我发现使用convert -list格式.所以我使用MacPorts重新安装了ImageMagick,并使用新的Paths to ImageMagick重新安装了rmagick.
