Hi, I’ve just started getting into rails and up until today (for some  
reason) I’ve been using Rails 1.2.6

So I updated to Rails 2.0.2 by using gem update, but now I’m not able to  
run anything at all.

Let’s say I create a new app by doing:  
“rails someApp”  
Then when I try to start the server, this is what I get:

thomas$ script/server  
=\> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)  
=\> Rails application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000)  
=\> Call with -d to detach  
=\> Ctrl-C to shutdown server  
\*\* Starting Mongrel listening at 0.0.0.0:3000  
\*\* Starting Rails with development environment…

I’ve searched around and I still haven’t found a working solution.  
Any help would be highly appreciated.

short version: it sounds like it’s installed gems from  
[gems.rubyonrails.org](http://gems.rubyonrails.org) which include edge gems that you probably don’t  
want unless you know what you’re doing  
Long version:

Thank’s for the reply.  
I’m actually installing from [gems.rubyforge.org](http://gems.rubyforge.org)

I also tried reinstalling rails all over, but without any result.

However, when I uninstalled Rails 2.0.2.9216 and was left with Rails  
2.0.2 it works fine.  
So I guess I’m good now.
