I have some issues while installing plugins. when i type

it comes up like this C:/InstantRails/ruby/lib/ruby/1.8/net/http.rb:560:in `initialize': Bad file desc riptor - connect(2) (Errno::EBADF)         from C:/InstantRails/ruby/lib/ruby/1.8/net/http.rb:560:in `open'         from C:/InstantRails/ruby/lib/ruby/1.8/net/http.rb:560:in `connect'         from C:/InstantRails/ruby/lib/ruby/1.8/timeout.rb:48:in `timeout'         from C:/InstantRails/ruby/lib/ruby/1.8/timeout.rb:76:in `timeout'         from C:/InstantRails/ruby/lib/ruby/1.8/net/http.rb:560:in `connect'         from C:/InstantRails/ruby/lib/ruby/1.8/net/http.rb:553:in `do_start'         from C:/InstantRails/ruby/lib/ruby/1.8/net/http.rb:542:in `start'         from C:/InstantRails/ruby/lib/ruby/1.8/open-uri.rb:242:in `open_http'          ... 13 levels...         from C:/InstantRails/ruby/lib/ruby/gems/1.8/gems/rails-2.0.2/lib/command s/plugin.rb:934         from C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require .rb:27:in `gem_original_require'         from C:/InstantRails/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require .rb:27:in `require'         from script/plugin:3

when i type

ruby script/plugin install calendar_helper

i get this:

Plugin not found: ["calendar_helper"]

I don't know if it's because i'm behind a proxy coz i have to use proxy to install rails through gem like this gem install rails --include-dependencies -p http:…

In fact, i've read almost all i can find and still can't figure it out. Before it drives me crazy, it there anyone who can help me out?

Thank you~ Matt

I find a way to install plugin via local files. But still, it will be much better if I can do it via internet.

Is there anyone who knows the answer?
