我最近升级到osx 10.8（Mtn Lion），现在我遇到了Imagemagick的问题。当我尝试上传文件时出现以下错误：识别错误回形针和Imagemagick
Command :: identify -format %wx%h '/var/folders/nd/1cw0mqzj0nb3jv8psz_ht9cr0000gn/T/2011Spring20120803-530-2nr1jn.jpg[0]'
[paperclip] An error was received while processing: #<Paperclip::Errors::NotIdentifiedByImageMagickError: /var/folders/nd/1cw0mqzj0nb3jv8psz_ht9cr0000gn/T/2011Spring20120803-530-2nr1jn.jpg is not recognized by the 'identify' command.>

我卸载/重新安装了自制软件和imagemagick。我甚至添加了rmagick宝石（我以前不需要）但仍然得到上述错误。
brew install imagemagick
Error: imagemagick-6.7.7-6 already installed
这里是酿造医生输出：
brew doctor
Warning: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
Warning: You have uncommitted modifications to Homebrew's core.
Unless you know what you are doing, you should run:
cd /usr/local && git reset --hard
Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
xml2-config
xmlcatalog
xmllint
xslt-config
xsltproc
Consider amending your PATH so that /usr/local/bin
occurs before /usr/bin in your PATH.
我甚至增加了以下我的config /环境/ development.rb文件
Paperclip.options[:command_path] = "/usr/local/bin"
我再次ImageMagick的卸载和重新安装它。现在我收到以下链接错误。
==> Installing imagemagick dependency: jpeg
dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

==> ./configure --prefix=/usr/local/Cellar/jpeg/8d
==> make install

当我键入酿造环节JPEG
Error: No such file or directory - /usr/local/Cellar/jpeg/8c
当我键入酿造环节的libtiff
Error: No such file or directory - /usr/local/Cellar/libtiff/3.9.5
因此，在总结的链接都在寻找旧版本的JPEG（8C代替8D的）和libtiff（3.9.5而不是4.0.2）
有关如何解决此问题的任何想法？

我重新安装了开发工具，甚至安装了最新版本的xcode 4.4 – prodigerati 2012-08-04 13:24:41
对不起，没有在家里使用mac，所以不能真正帮助。我隐约记得有一个朋友有类似的问题，下次我跟她聊天时，我可能会挖掘一些东西。 – 2012-08-04 13:45:11
