↑ここをみると

require 'RMagick.so'

となっていて、これがエラーする。


つまり、以下が解決できればいい。

# irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'RMagick.so'
LoadError: no such file to load -- RMagick.so
       from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require'
       from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
       from (irb):3
irb(main):004:0>

これが、

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'RMagick.so'
=> true

こうなるようにしよう。


RMagickの Install FAQ を見てみる

http://rmagick.rubyforge.org/install-faq.html#loaderror
↑ここが一番あやしいけど、

export LD_LIBRARY_PATH=/usr/local/lib

やってもだめ・・・・orz



ImageMagick と RMagick を再インストール

色々調べた結果・・・分からず・・・orz
もう・・・再インストールしかない・・・。

  • RMagick のアンインストール
# gem uninstall rmagick
# rpm -qa | grep ImageMagick
ImageMagick-perl-6.0.7.1-16
ImageMagick-devel-6.0.7.1-16
ImageMagick-6.0.7.1-16
# rpm -e ImageMagick-perl-6.0.7.1-16
# rpm -e ImageMagick-devel-6.0.7.1-16
# rpm -e ImageMagick-6.0.7.1-16
# rpm -qa | grep ImageMagick
#
# yum install ImageMagick
# yum install ImageMagick-devel
# yum install ghostscript*
  • RMagick インストール
# gem install RMagick -v 1.13.0
Need to update 1 gems from http://gems.rubyforge.org
.
complete
Building native extensions.  This could take a while...
Successfully installed rmagick-1.13.0

おおおおおおぉ、ちゃんと入った！

# rpm -qa | grep ImageMagick
ImageMagick-devel-6.0.7.1-16
ImageMagick-6.0.7.1-16
# gem list | grep rmagick
rmagick (1.13.0)

※ImageMagick-perl-6.0.7.1-16 はいまのところ必要ないのでインストールはしませんでした。

  • ちゃんと require できるか確認する
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'RMagick.so'
=> true


できましたー。

しかし、根本的な原因が分からず・・・。
なぜ、とつぜん動かなくなるのか・・・。

つっこみ歓迎です。
