在Centos 5上安装RMagick ruby​​gem的问题

Question

我在Centos 5上安装RMagick ruby​​gem时遇到问题.我已经按照http://rmagick.rubyforge.org/install2-linux.html中详述的步骤进行了操作,但是当我尝试:

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但我无法看到rubygems.我尝试了以下但结果是一样的:

sudo gem install rmagick -- --with-opt-dir=/usr/local/bin

任何建议,将不胜感激.

我最近将ImageMagick 6.5.4.7从CentOS6向后移植到CentOS5,所以现在安装rmagick会更容易:

rpm -Uvh http://rbel.co/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel
gem install rmagick

Answer 2

所以我终于设法安装了rmagick ruby​​gem的版本1.15.17!这是我做的:

1. 卸载了ImageMagick 6.5.4-9以及我从源代码安装的委托库
2. sudo yum install ImageMagick
3. sudo yum install ImageMagick-devel
4. curl -O http://www.zacharywhitley.com/linux/rpms/fedora/core/6/i386/msttcorefonts-2.0-1.noarch.rpm
5. sudo rpm -ivh msttcorefonts-2.0-1.noarch.rpm
6. ln -s /usr/share/fonts/msttcorefonts/ /usr/share/fonts/default/TrueType
7. sudo gem install rmagick -v 1.15.17 --no-rdoc --no-ri

rubiojr的答案对我有用,但rbel.co目前正在下降.您可以使用rbel.frameos.org代替:

rpm -Uvh http://rbel.frameos.org/rbel5
yum install ImageMagick-devel ImageMagick-c++-devel
gem install rmagick
