解决方法
1.安装ruby软件包
[root@redis ~]#yum -y install ruby
2.安装rubygems软件包
[root@redis~]#tar -zxvf rubygems-2.2.2.tar
[root@redis ~]# cd rubygems-2.2.2
[root@redis rubygems-2.2.2]# ls

=== 2.2.1 / 2014-01-06
Bug fixes:
* Platforms in the Gemfile.lock GEM section are now handled correctly. Bug
#767 by Diego Viola.
* RubyGems now displays which gem couldn't be uninstalled from the home
directory. Pull request #757 by Michal Papis.
* Removed unused method Gem::Resolver#find_conflict_state. Pull request #759
by Smit Shah.
* Fixed installing gems from local files without dependencies. Issue #760 by
Arash Mousavi, pull request #764 by Tim Moore.
* Removed TODO about syntax that works in Ruby 1.8.7. Pull request #765 by
Benjamin Fleischer.
* Switched Gem.ruby_api_version to use RbConfig::CONFIG['ruby_version'] which
has the same value but is overridable by packagers through
--with-ruby-version= when configuring ruby. Bug #770 by Jeremy Evans.
* RubyGems now prefers the bundler API for `gem install` to reduce HTTP
requests. (This change was intended for RubyGems 2.2.0 but was missed.)
This should address bug #762 by Dan Peterson and bug #766 by mipearson.
* Added Gem::BasicSpecification#source_paths so documentation or analysis
tools can work properly as require_paths no longer returns extension source
directories. Bug #758 Vít Ondruch.
* Gem.read_binary can read read-only files again. This caused file://
repositories to stop working. Bug #761 by John Anderson.
* Fixed specification file sorting for Ruby 1.8.7 compatibility. Pull
request #763 by James Mead
=== 2.2.0 / 2013-12-26
Special thanks to Vít Ondruch and Michal Papis for testing and finding bugs in
RubyGems as it was prepared for the 2.2.0 release.
Major enhancements:
* RubyGems can check for gem dependencies files (gem.deps.rb or Gemfile) when
rubygems executables are started and uses the found dependencies. This
means `rake` will work similar to `bundle exec rake`. To enable this set
the `RUBYGEMS_GEMDEPS` environment variable to the location of your
dependencies file.
See Gem::use_gemdeps for further details.
* A RubyGems directory may now be shared amongst multiple ruby versions. Upon
activation RubyGems will automatically compile missing extensions for the
current platform when the built objects are missing. Issue #596 by Michal
Papis
By default different platforms do not share gem install locations so this
must be configured by setting GEM_HOME to a common directory. Some gems use
fixed paths for requiring extensions and are not compatible with sharing gem
directories.
The default sharing location may be configured by RubyGems packagers through
Gem.default_ext_dir_for. Pull Request #744 by Vít Ondruch.
Minor enhancements:
* RubyGems checks the 'allowed_push_host' metadata value when pushing a gem to
prevent an accidental push to a public repository (such as rubygems.org).
If you have private gems you should set this value in your gem specification
metadata. Pull request #603 by Seamus Abshere.
* `gem list` now shows results for multiple arguments. Pull request #604 by
Zach Rabinovich.
* `gem pristine --extensions` will restore only gems with extensions. Issue
#619 by Postmodern.
* Gem::Specification#files is now sorted. Pull request #612 by Justin George.
* For `gem list` and friends, "LOCAL" and "REMOTE" headers are omitted if
only local or remote gem information is requested with --quiet. Pull
request #615 by Michal Papis.
* Added Gem::Specification#full_require_paths which is like require_paths, but
returns a fully-qualified results. Pull request #632 by Vít Ondruch.
* RubyGems now looks for the https_proxy environment variable for https://
sources. RubyGems will fall back to http_proxy if there is no https_proxy.
Issue #610 by mkristian.
* RubyGems now creates directories in .gem files. Issue #631 by marksolaris.
* RubyGems raises an exception when a specification includes its gem. Issue
#623 by notEthan.
* RubyGems now displays relevant release note information when updating
RubyGems. Issue #647 by Trevor Wennblom.
* Deprecated Gem::Installer::ExtensionBuildError in favor of
Gem::Ext::BuildError. The old constant is an alias for the new constant.
* When extensions are built the gem_make.out file is always written now, even
on success. This will help with debugging bad builds that report success.
* If a specification fails to validate RubyGems shows a link to the
specification reference guide. Issue #656 by Markus Heiler.
* When using `gem install -g`, RubyGems now detects the presence of an
Isolate, Gemfile or gem.deps.rb file.
* Added Gem::StubSpecification#stubbed? to help determine if a user should run
`gem pristine` to speed up gem loading. Pull request #694 and #701 by Jon
Leighton.
* RubyGems now warns when a gem has a pessimistic version dependency that may
be too strict.
* RubyGems now warns when a gem has an open-ended dependency.
* RubyGems now raises an exception when a dependency for a gem is defined
twice.
* Marked the license specification attribute as recommended. Pull request
#713 by Benjamin Fleischer.
* RubyGems uses io/console instead of `stty` when available. Pull request
#740 by Nobuyoshi Nakada
* Relaxed Gem.ruby tests for platforms that override where ruby lives. Pull
Request #755 by strzibny.
Bug fixes:
* RubyGems now returns an error status when any file given to `gem which`
cannot be found. Ruby bug #9004 by Eugene Vilensky.
* Fixed command escaping when building rake extensions. Pull request #721 by
Dmitry Ratnikov.
* Fixed uninstallation of gems when GEM_HOME is a relative directory. Issue
#708 by Ryan Davis.
* Default gems are now ignored by Gem::Validator#alien. Issue #717 by David
Bahar.
* Fixed typos in RubyGems. Pull requests #723, #725, #731 by Akira Matsuda,
pull request #736 by Leo Gallucci, pull request #746 by DV Suresh.
* RubyGems now holds exclusive locks on cached gem files to prevent incorrect
updates. Pull Request #737 by Smit Shah
* Improved speed of `gem install --ignore-dependencies`. Patch by Terence
Lee.
------------------------------------------------------------------------------
RubyGems installed the following executables:
/usr/bin/gem
Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
ri Classname
ri Classname.class_method
ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.
