Gem是一个管理Ruby库和程序的标准包,它通过Ruby Gem(如 http://rubygems.org/ )源来查找、安装、升级和卸载软件包,非常的便捷。
Ruby 1.9.2版本默认已安装Ruby Gem,如果你的版本低于这个?那就往下看吧
安装gem 需要ruby的版本在 1.8.7 以上,默认的centos5 上都是1.8.5 版本,所以首先你的升级你的ruby ,有两种方式,yum 和 tar包,
如果你直接用yum的话,一般是装不上的,得先做些准备,首先添加一个源
- CentOS6/RedHat6系列安装:
- rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
- CentOS5/RedHat5系列安装:
- rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
- 安装后编辑epel.repo
- vi /etc/yum.repos.d/epel.repo
- 修改 enabled=1

上面的执行完成后,就可以安装了
- #yum install rubygems
- ok 测试一下吧
- # /usr/bin/gem install sinatra
- Successfully installed rack-1.5.2
- Successfully installed rack-protection-1.5.0
- Successfully installed tilt-1.3.5
- Successfully installed sinatra-1.3.5
- 4 gems installed
- Installing ri documentation for rack-1.5.2...
- Installing ri documentation for rack-protection-1.5.0...
- Installing ri documentation for tilt-1.3.5...
- Installing ri documentation for sinatra-1.3.5...
- unrecognized option `--encoding=UTF-8'
- For help on options, try 'rdoc --help'
好了 可以用gem 来安装ruby的东东了,一般的ruby程序都有 Gemfile,可以用下面的方法把所有需要的东西都装上,拿 kibana 为例
- # cd /soft/Kibana-0.2.0
- # ls Gemfile
- Gemfile
文件存在,好了,直接执行命令吧
- # /usr/bin/gem install bundler
- Successfully installed bundler-1.3.4
- 1 gem installed
- Installing ri documentation for bundler-1.3.4...
- Installing RDoc documentation for bundler-1.3.4...
- # /usr/bin/bundle
