Mechanize

あたらしい鯖にmechanizeをインストールしようとしたら躓いたのでメモ

[root@localhost rubygems-1.3.1]# gem install mechanize

Building native extensions. This could take a while...

ERROR: Error installing mechanize:

ERROR: Failed to build gem native extension.

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

･･･省略

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/nokogiri-1.2.3 for inspection.

libxml2を入れてくれ？おにぎり？あ、のこぎりか。

yum install libxml2

･･･

Package libxml2 - 2.6.26-2.1.2.7.i386 is already installed.

ん？既にはいってるって。

yum install libxml2-devel

んーーnokogiriをパーサとして使うらしいのでgem
