JPEG 无法被识别、回形针、ImageMagick on Rails 3.1.3 OSX Mountain Lion 识别

Question

我已经浏览了所有关于此的 SO 问题，但没有任何乐趣。

升级到 Mountain Lion 后出现以下错误：

Validation failed: Photo /var/folders/92/qp3ppxv92tsglvj03ndp0t6m0000gn/T/stream20121007-36927-1dzwbgk-0.jpeg is not recognized by the 'identify' command.

在日志中

Command :: identify -format %wx%h :file
[paperclip] An error was received while processing: #    <Paperclip::NotIdentifiedByImageMagickError: /var/folders/92/qp3ppxv92tsglvj03ndp0t6m0000gn/T/stream20121007-36927-1dzwbgk-0.jpeg is not recognized by the 'identify' command.>

我正在使用：Ruby 1.8.7、Rails 3.1.3、OSX Mountain Lion、Homebrew 来安装依赖项

我已经添加了

#development.rb
Paperclip.options[:command_path] = "/usr/local/bin"

我已完全删除并重新安装自制软件

#brew doctor
Your system is raring to brew.

#brew list

ack     gettext     imagemagick libffi      libpng      little-cms  pkg-config  readline
cmake       git     jasper      liblqr      libtiff     mysql       postgresql  xz
freetype    glib        jpeg        libmagic    libyaml     ossp-uuid   qt

我在另一个 SO 案例的推荐下安装了 liblqr，这带来了很多依赖。

Identify 似乎可以从命令行工作

#identify /var/folders/92/qp3ppxv92tsglvj03ndp0t6m0000gn/T/stream20121007-36927-1dzwbgk-0.jpeg
/var/folders/92/qp3ppxv92tsglvj03ndp0t6m0000gn/T/stream20121007-36927-1dzwbgk-0.jpeg JPEG 259x195 259x195+0+0 8-bit DirectClass 11KB 0.000u 0:00.000

#identify -format %wx%h  /var/folders/92/qp3ppxv92tsglvj03ndp0t6m0000gn/T/stream20121007-36927-1dzwbgk-0.jpeg
259x195

识别似乎可以从控制台工作

Loading development environment (Rails 3.1.3) 1.8.7 :001 > system("identify -format %wx%h /var/folders/92/qp3ppxv92tsglvj03ndp0t6m0000gn/T/stream20121007-36927-1dzwbgk-0.jpeg") 259x195 => true

我已经安装了 rmagick - 虽然我以前从未使用过它。宝石：

*** LOCAL GEMS *** 
paperclip (2.7.1)
rmagick (2.13.1)

我已经尝试了所有建议，现在完全没有想法。关于如何深入挖掘以隔离问题的任何建议？原因是由 Paperclip 导致调整 jpeg 或 PNG 文件的大小（我没有尝试过任何其他文件）：

has_attached_file :photo, :styles => {:thumb => "100x100", :medium => "x140", :mediumplus => "x210",:large => "960x378" }, :storage => :s3, :s3_credentials => { :access_key_id => ENV['S3_KEY'], :secret_access_key => ENV['S3_SECRET'] }, :s3_protocol => "https", :bucket => ENV['S3_BUCKET'], :path => ":attachment/:id/:style.:extension"

Answer 1

使用回形针 2.8.0 而不是 2.7.1。
