ruby-on-rails - 在 Ubuntu 10.04 上使用 graphicsmagick 安装 rmagick 2.13.1

Question

我之前有一个与 ImageMagick 一起使用的 rmagick gem 安装。 ImageMagick 是在禁用 OpenMP 的情况下从源代码安装的。此安装工作顺利。然而，我试图卸载 rmagick 和 ImageMagick，这样我就可以拥有一个适用于 GraphicsMagick 的版本。

所以我从源代码安装了 GraphicsMagick 并再次禁用了 OpenMP 功能。但是，当我安装 rmagick 时，我得到以下信息:

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick-2.13.1.gem:

Can't install RMagick 2.13.1. Can't find MagickWand.h.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog
        --srcdir=.
        --curdir
        --ruby=/usr/bin/ruby1.8

我已经尝试运行:

 export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

并检查文件夹 pkgconfig 的内容:

freetype2.pc  GraphicsMagick.pc  GraphicsMagick++.pc  GraphicsMagickWand.pc  libpng15.pc  libpng.pc

我在这里错过了什么？

安装完libmagickwand-dev后再尝试安装
