【问题描述】：
我最近升级到 osx 10.8 (Mtn Lion)，现在我遇到了 Imagemagick 问题。尝试上传文件时出现以下错误：
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.>
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。我什至添加了 rmagick gem（我以前不需要），但仍然出现上述错误。
brew install imagemagick
Error: imagemagick-6.7.7-6 already installed
这是 brew doctor 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.
我什至在我的 config/environments/development.rb 文件中添加了以下内容
Paperclip.options[:command_path] = "/usr/local/bin"
我再次卸载了 Imagemagick 并重新安装了它。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
==> Downloading http://www.ijg.org/files/jpegsrc.v8d.tar.gz

==> ./configure --prefix=/usr/local/Cellar/jpeg/8d
==> make install
Error: The linking step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link jpeg'
==> Summary

==> Installing imagemagick dependency: libtiff

==> Downloading http://download.osgeo.org/libtiff/tiff-4.0.2.tar.gz

Error: You must `brew link jpeg' before little-cms can be installed
当我输入 brew link jpeg
Error: No such file or directory - /usr/local/Cellar/jpeg/8c
当我输入 brew link libtiff 时
Error: No such file or directory - /usr/local/Cellar/libtiff/3.9.5
总之，这些链接正在寻找旧版本的 jpeg（8c 而不是 8d）和 libtiff（3.9.5 而不是 4.0.2）
关于如何解决这个问题的任何想法？
【问题讨论】：
-
我重新安装了开发者工具，甚至安装了最新版本的xcode 4.4
-
很抱歉没有在家里使用 Mac，所以帮不上忙。依稀记得有个朋友也有类似的问题，下次跟她聊天说不定能挖点东西。
