gem install rails 不能装成功

F:/ruby_design_env>gem install rails
WARNING: RubyGems 1.2+ index not found for:

RubyGems will revert to legacy indexes degrading performance.
Bulk updating Gem source index for: http://gems.rubyforge.org/
ERROR: While executing gem ... (NoMethodError)
undefined method `gems' for #<Array:0x4515a08>

只能下载gem包，然后手动装

gem install --local rails-2.3.4.gem

无奈还有一些depend的包，在 http://rubyforge.org都能找得到的，装完下面的包rails就能装成功了

actionmailer-2.3.4.gem

actionpack-2.3.4.gem

activerecord-2.3.4.gem

activeresource-2.3.4.gem

activesupport-2.3.4.gem

rack-1.0.1.gem

rake-0.8.7.gem
