Hi All,

I backed up my rails project and then reinstall Windows due to OS crash.  
Then I install the latest Ruby, RubyGem, and Rails and copy back the  
rails project. But now I cannot start the server (ruby script/server).  
It gives the following message:

./script/…/config/boot.rb:26:Warning: Gem:SourceIndex#search support  
for String patterns is deprecated Cannot find gem for Rails ~\>1.3.1.0:  
Install the missing gem with ‘gem install -v=1.3.1 rails’, or change  
environment.rb to define RAILS\_GEM\_VERSION with your desired location.

I changed environment.rb’s RAILS\_GEM\_VERSION to 1.3.1 but it does not  
have an effect. Then I tried to install the missing gem as listed above  
(I think it is already installed but I try it anyway) and got the error  
message: Could not find gem rails locally or in a depository.

How can I solve this problem? Should I start a new app for my existing  
project?  
Please enlighten. Thanks!

Andreas,

RAILS\_GEM\_VERSION should match the version number of your installed  
rails. i.e.: on my system,  
rails --version gives Rails 2.2.2  
thus, RAILS\_GEM\_VERSION = ‘2.2.2’ is correct.

1.3.1 is probably the version of gem you have installed
