Gem installation Problem / Controller generation problem

[unnikrishnanes]

I am new to ROR.


I Have ruby and instant rails installed in my system(I am using Windows). I have created an application 'railslist'
[command i used:- c:\development\rails railslist ]

But when I tried to generate a controller
[ c:\development\railslist\ruby script/generate controller App ] I got the following error

------------------------------------------------
Cannot find gem for Rails ~>1.2.3.0:
Install the missing gem with 'gem install -v=1.2.3 rails', or
change environment.rb to define RAILS_GEM_VERSION with your desired version.

-----------------------------------------------

Actually my gem version is 0.9.2 which i knew using the command 'gem -v'

and i tried 'gem install rails --include-dependencies' too and got another error as follows


-----------------------
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Bad file descriptor - connect(2)(Errno::EBADF)

----------------------


I dont know wht the problem could be...

Please help
