我在Centos 5上安装RMagick rubygem时遇到了问题。我已经按照http://rmagick.rubyforge.org/install2-linux.html中详细介绍的步骤进行了操作,但是当我尝试的时候:
sudo gem install rmagick
结果是:
Building native extensions. This could take a while...
ERROR: Error installing rmagick:
ERROR: Failed to build gem native extension.
/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes
checking for Magick-config... no
Can't install RMagick 2.11.0. Can't find Magick-config in /usr/bin:/bin
*** extconf.rb failed ***
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/local/bin/ruby
Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.11.0 for inspection.
Results logged to /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.11.0/ext/RMagick/gem_make.out
目录/usr/local/bin包含Magick-config,但我无法让rubygems查看该目录。我尝试了以下方法,但结果是相同的:
sudo gem install rmagick -- --with-opt-dir=/usr/local/bin
如有任何建议,我们将不胜感激。

我最近从CentOS6向后移植了ImageMagick 6.5.4.7到CentOS5,所以现在安装rmagick应该会更容易:
rpm -Uvh http://rbel.co/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel
gem install rmagick

answer from rubiojr对我来说是有效的,但rbel.co目前出现了故障。您可以改用rbel.frameos.org:
rpm -Uvh http://rbel.frameos.org/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel
gem install rmagick

在遵循投票最多的答案中的说明后,一直收到此错误:
RMagick: unable to read font `(null)'.
因此,我有一些东西要添加到步骤7,取自David Bock博客的更新:
gem install rmagick -v 1.15.17 --no-rdoc --no-ri -- --disable-htmldoc
如果您的字体文件使rmagick不满意,禁用html文档对于避免进一步的错误至关重要。这是我花了大约2个小时解决这个问题的结果。
