Spree::Admin::ImagesController#create中的曲别针：：NotIdentifiedByImageMagickError

Question

我正在尝试第一次设置Spree。一切都很顺利，直到我点击上传图片。我已经在Mac OSX Mountain Lion上使用自制软件安装了Imageamgick。上传任何图像都会出现以下错误。

Paperclip::NotIdentifiedByImageMagickError in Spree::Admin::ImagesController#create

    Command :: identify -format %wx%h :file
[paperclip] An error was received while processing: #<Paperclip::NotIdentifiedByImageMagickError: /var/folders/fq/9g_6hmg513g6137rb6sbghw00000gn/T/stream20121005-26943-16883d4.png is not recognized by the 'identify' command.>

Paperclip::NotIdentifiedByImageMagickError (/var/folders/fq/9g_6hmg513g6137rb6sbghw00000gn/T/stream20121005-26943-16883d4.png is not recognized by the 'identify' command.):

当我从命令行运行identify时，我得到了以下输出

    Image Settings:
  -alpha option        on, activate, off, deactivate, set, opaque, copy
                       transparent, extract, background, or shape

  -list type           print a list of supported option arguments
  -log format          format of debugging information
  -version             print version information

By default, the image format of `file' is determined by its magic
number.  To specify a particular image format, precede the filename
with an image format name and a colon (i.e. ps:image) or specify the
image type as the filename suffix (i.e. image.ps).  Specify 'file' as
'-' for standard input or output.

任何帮助都将不胜感激。

谢谢，科里

我的错误是Spree::Admin::ImagesController”中的-“Paperclip::NotIdentifiedByImageMagickError

几天前我修复了这个错误。

在此之前，我尝试过：

• 更新
• etc

(使用命令行工具)

• 更新Imagemagick (我从源代码和二进制模块中尝试过)

• 更新MacPort

• 使用Brew (刷新Imagemagick的所有依赖项，使用“brew医生”)，而不是MacPort

<代码>H111重新安装使用Imagemagick的所有gem<代码>H212<代码>H113包更新gem

当然，我在production.rb文件中有指向Imagemagick bin文件夹的“Paperclip::Attachment.default_options:command_path”选项。

我从头到尾做了几次，一次又一次。

但什么也帮不了我。

顺便说一下，在所有情况下，我都能很好地处理任何类型的测试图像的“转换”、“识别”和“显示”，但不是在我的rails应用程序(spree app)中。

我深入研究了dipper，并尝试在rails控制台中使用

Paperclip.run("identify", "-format %m :file", :file => "/path/to/image”) 

就像回形针一样。并且仅此命令的新格式(cocaine 0.4)：

Paperclip.run("identify", "-format %m /path/to/image")

工作得很好！

结果，我发现cocaine 0.4是我的问题的根源。我试着在我的Gemfile中降级到0.3.2，我的Spree应用程序开始工作了！

我需要做的就是使用0.3.2而不是0.4！

检查png格式是否在identify的编译格式列表中：

identify -list format

如果不是，您可能需要使用以下选项重新编译它：

./configure --prefix=/usr/local --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes

Answer 3

我还遇到了图像文件不存在于公共文件夹中的问题。

我刚刚复制了一个具有相同名称的随机文件，然后一切都开始工作了。

parepclip 2.7.5 cocain 0.3.2
