RubyGems是一个方便而强大的Ruby程序包管理器（ package manager），类似RedHat的RPM.它将一个Ruby应用程序打包到一个gem里，作为一个安装单元。当前最新版本为0.8.3下载地址：http://rubyforge.org/frs/?group_id=126主页：http://rubygems.rubyforge.org/wiki/wiki.pl最新的Ruby版本已经包含RubyGems了。
特点：
能远程安装包
包之间依赖关系的管理
简单可靠的卸载（uninstallation）查询机制，能查询本地和远程服务器的包信息能保持一个包的不同版本基于Web的查看接口，能查看你安装的gem的信息。安装RubyGems首先从rubyforge下载它的源文件 ，然后解压缩到一个地方，比如C:rubygems-0.8.3C:rubygems-0.8.3>ruby setup.rb---> bin<--- bin---> lib---> lib/rubygems<--- lib/rubygems<--- lib---> bin<--- bin---> lib---> lib/rubygems<--- lib/rubygems<--- librm -f InstalledFiles---> binmkdir -p c:/ruby/bin/install gem c:/ruby/bin/install gem_server c:/ruby/bin/install generate_yaml_index.rb c:/ruby/bin/install update_rubygems c:/ruby/bin/<--- bin---> libmkdir -p c:/ruby/lib/ruby/site_ruby/1.8/install rubygems.rb c:/ruby/lib/ruby/site_ruby/1.8/install ubygems.rb c:/ruby/lib/ruby/site_ruby/1.8/---> lib/rubygemsmkdir -p c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall builder.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall cmd_manager.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall command.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall config_file.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall doc_manager.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall format.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall gem_commands.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall gem_runner.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall installer.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall loadpath_manager.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall old_format.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall open-uri.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall package.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall remote_installer.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall rubygems_version.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall source_index.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall specification.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall user_interaction.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall validator.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygemsinstall version.rb c:/ruby/lib/ruby/site_ruby/1.8/rubygems<--- lib/rubygems<--- libAs of RubyGems 0.8.0, library stubs are no longer needed.Searching $LOAD_PATH for stubs to optionally delete (may take a while)......done.No library stubs found. Successfully built RubyGem Name: sources Version: 0.0.1 File: sources-0.0.1.gemC:rubygems-0.8.3>gem -v0.8.3安装其实很简单。使用也简单，不带参数运行gem则显示使用方法：C:rubygems-0.8.3>gem
