我已經(jīng)安裝了ImageMagick ImageMagick的使用安裝腳本，我在OSX 10.7獅子，采用RVM，ruby1.9.3p125。 這個問題似乎是與MagickWand.h有關(guān)
這里是日志

details. You may need configuration options.

以下是嘗試：
1 我建議沖泡管理您的二進制文件的依賴關(guān)系。您可以輕松地與釀造安裝ImageMagick的，就像這樣：
brew install imagemagick

這是我對我的系統(tǒng)：
imagemagick 6.7.1-1 CodeGo.net Depends on: jpeg, libtiff, little-cms, jasper/usr/local/Cellar/imagemagick/6.7.1-1 (1389 files, 32M) CodeGo.net

和我有設置為你的機器和ruby版本的條款。

2.解決這個設定包括您目前的ImageMagick的安裝路徑：
與釀造ImageMagick的安裝brew install imagemagick

查找圖書館
$ mdfind MagickWand.h/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/wand/MagickWand.h

安裝的RMagickgem
$ C_INCLUDE_PATH=/path gem install rmagick

例如：
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/ gem install rmagick

3.如果您收到包裝xxx
未找到。 找到包，并添加它到目錄路徑PKG_CONFIG_PATH
在你的變量~/.bash_login
或~/.bash_profile
文件中。 例如： 如果你得到的錯誤：Package MagickCore was not found in the pkg-config search path.

尋找到的文件是：$ mdfind magickcore.pc/usr/local/homebrew/Cellar/imagemagick/6.7.7-6/lib/pkgconfig/MagickCore.pc

添加到您的bash_login或bash_profile文件：export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:/usr/local/homebrew/Cellar/imagemagick/6.7.7-6/lib/pkgconfig/:$PKG_CONFIG_PATH"
源的bash_login / profile文件

1）由安裝程序進行安裝 2）盡量創(chuàng)業(yè)板安裝的RMagick 如果檢查棒/ MagickWand.h ...無 類型mdfind MagickWand.h
找到喜歡的東西/Users/user/ImageMagick-6.8.3/include/ImageMagick-6/wand/MagickWand.h

并在終端C_INCLUDE_PATH=/Users/user/ImageMagick-6.8.3/include/ImageMagick-6/ gem install rmagick

如果，以后你有這樣的錯誤（一個有它）“包裝MagickCore沒有在pkg配置搜索路徑中找到?！?類型mdfind MagickCore.pc

找到喜歡的東西的/ opt / ImageMagick的/ lib中/ pkgconfig / MagickCore.pc 終于在終端中輸入：PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig/ gem install rmagick

5.當我反對這個問題，它無法找到MagickCore.pc，所以我這樣做;$ mdfind MagickCore.h/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/magick/MagickCore.h/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/magick/MagickCore.h$ export PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/$ gem install rmagick

和它的工作！
6.我不得不添加兩個ENV變量，使其工作。這樣C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/ PKG_CONFIG_PATH=/opt/local/lib/pkgconfig:/usr/local/Cellar/imagemagick/6.7.7-6/lib/pkgconfig/ gem install rmagick
