Hi all, Somebody please advice me what should i do:

I installed instant rails and i executed the command “\*ruby  
script/server” \*sucessfully  
for the first time

the next time, when i tried to execute the same command, it gave me the  
error : “Cannot find Gem for rails =1.1.2: Install the missing Gem with  
‘Gem  
install -v=1.1.2 rails’ or change your Environment.rb to defined  
RAIL\_GEM\_VERSION with your desired version”

the other problem is: when i execute ‘Gem install -v=1.1.2 rails’ , it  
gives  
error message: “ERROR:While executing gem … (Errno::EBADF) Bad File  
descripor - connect (2)”

You’re trying to use a rails app that has been tied to a specific  
version of Rails (1.1.2 in your case, when you have probably  
installed 1.1.4). Simplest solution is to find the line calling out  
that version in config/envrionment.rb and comment it out with a #.

This can happen if you are not connected to the internet.

If you are connected but still get this then you might be behind a  
firewall/proxy-server. If so you need to tell the gem command the  
address  
and port of your proxy server. I don’t remember the option you need to  
use,  
you’ll have to look it up (or maybe someone else remembers).
