centos 6.3下安装ruby

1 首先安装yaml

yum install libyaml

从ruby官网下载最新版本的ruby 包 1.9.3版本

tar zxvf解压

配置路径

./configure--prefix=/usr/local/ruby

编译再安装

make

make install

/usr/local/ruby目录下查看ruby版本以及gem版本

rbuy -v查看版本信息

修改PATH，把ruby的bin路径添加到PATH中

vi /etc/profile

最后加上

PATH=/usr/local/ruby/bin:$PATH

export PATH

gem help install 出现错误，  需要ruby-zlib

出现如下错误 是因为 系统需要

[root@localhost zlib]# rpm -qa | grep zlib
zlib-1.2.3-27.el6.i686
zlib-devel-1.2.3-27.el6.i686
