centos yum install nokogiri 1.5.8 不成功的解决方案

centos下安装nokogiri不成功，提示如下：

gem install nokogiri -v 1.5.8

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

ERROR:  Error installing nokogiri:

        ERROR: Failed to build gem native extension.

 

    /usr/local/rvm/rubies/ruby-1.9.3-p545/bin/ruby extconf.rb

checking for libxml/parser.h... no

-----

libxml2 is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

-----

*** 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.

 

 

解决方案：

 

yum -y install gcc gcc-c++ zlib-devel openssl-devel readline-devel libxml2 libxml2-devel libxslt libxslt-devel

 

是因为缺少编译环境，解决了：

 

gem install nokogiri -v 1.5.8
