Greetings,

I have my rails 3 newly installed, everything seemed working except I  
tried start thin server:

~/test/rails3\_1.9$ script/rails server thin  
Exiting  
/var/lib/gems/1.9.1/gems/rack-1.2.1/lib/rack/handler/thin.rb:1:in

`<top (required)>' from script/rails:6:in`require’  
from script/rails:6:in `’

I have thin gem installed:  
thin (1.2.7)

Could anyone tell me what is the problem? Thanks in advance.

I hope I am not saying something totally wrong and idiotic but here  
goes: Is  
that Ruby 1.9.1 you are using? If I understand Rails 3 wants either  
1.8.7 or  
1.9.2. Could that be the problem?

Hello David,

ruby 1.9.1 of Debian is actually 1.9.2 and I can run rails using:  
/var/lib/gem/1.9.1/bin/thin start to start the thin server.

~/test/rails3\_1.9$ ruby1.9.1 -v  
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86\_64-linux]

I do not know why.

Interesting. Sorry could not be more help. I did just try installing the  
gem  
and it runs on my 1.9.2-p0, but I am on a mac.

You have to add thin in the Gemfile file in your rails root, then  
“rails server thin” will work fine:

gem ‘thin’

Whithout this, doing a “thin start” inside your rails root should also  
work fine.
