thin server claims I don''t have correct rails gem installed

Hi everyone, I need some insight into a problem I just started having.

I''m running ruby 1.8.6 on an ubuntu box with the following gems
installed:

$ sudo gem list --local

*** LOCAL GEMS ***

actionmailer (2.3.5, 2.3.4, 2.3.2, 2.2.2)
actionpack (2.3.5, 2.3.4, 2.3.2, 2.2.2)
activerecord (2.3.5, 2.3.4, 2.3.2, 2.2.2)
activeresource (2.3.5, 2.3.4, 2.3.2, 2.2.2)
activesupport (2.3.5, 2.3.4, 2.3.2, 2.2.2)

capistrano (2.5.11, 2.5.10, 2.5.5)
columnize (0.3.1, 0.3.0)
daemons (1.0.10)
eventmachine (0.12.10, 0.12.6)
ezcrypto (0.7.2)
gem_plugin (0.2.3)
highline (1.5.1)
linecache (0.43)
mocha (0.9.8)
net-scp (1.0.2)
net-sftp (2.0.4, 2.0.2)
net-ssh (2.0.17, 2.0.16, 2.0.11)
net-ssh-gateway (1.0.1)
pdf-reader (0.8.2, 0.8.1)
prawn (0.7.1, 0.6.3)

rails (2.3.5, 2.3.4, 2.3.2, 2.2.2)
rake (0.8.7, 0.8.4, 0.8.3)
rghost (0.8.7.2, 0.8.6.5, 0.8.6.3)

sqlite3-ruby (1.2.5, 1.2.4)
test-spec (0.10.0)
thin (1.2.5, 1.0.0)


I''ve got a rails 2.3.5 app that I''ve developed and that runs
fine
using the traditional WEBrick "script/server" command. However, if I
try to run thin:

$ thin -v
thin 1.2.5 codename This Is Not A Web Server
$ thin start>> Using rails adapterMissing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`,
update your RAILS_GEM_VERSION setting in config/environment.rb for the
Rails version you do have installed, or comment out RAILS_GEM_VERSION
to use the latest version installed.


This is just crazy as I certainly DO have rails 2.3.5 gem installed
(as displayed above). Now, it is true that I have ruby 1.9.0 installed
on the box as well and no 1.9 gems installed. However, I am most
certainly running everything in ruby 1.8.6.

Where else should I look to figure this problem out?

Re: thin server claims I don''t have correct rails gem installed

do you have your rails version set in config/environment.rb as the
error suggests?  you could also freeze rails to the vendor dir.
do you get the same gems with:
$ gem list

Alright, tried this for kicks. Got some interesting results:

$ rake rails:freeze:gems
(in /data/production/gfeworksheet)
Freezing to the gems for Rails 2.3.5
rm -rf vendor/rails
mkdir -p vendor/rails
cd vendor/rails

cd -

Make sure script/server still works:

Now test thin:

Still doesn''t work but at least now I have a stack trace with some
interesting stuff to poke around in. Thanks for the idea!

So I did to an upgrade of my gems today which installed rack 1.1.0. So
I''m guessing the "require_frameworks" code is trying to pull
in both
1.0.1 (first) then 1.1.0, causing a conflict..?

So, I uninstalled rack 1.1.0 and retried it... works like a charm!
Problem (or at least MY problem) solved.

I ran into this issue as well after installing rack 1.1.0. As noted, 
reverting to 1.0.1 seems to work as a workaround. However, the real 
cause seems to be that rails 2.3 is declaring that it is not compatible 
with rack 1.1.0. Thin itself seems to work fine--- I have a thin-sinatra 
app running with rack 1.1.0 with no problems. What appears to happen on 
a thin-rails stack is that thin loads rack 1.1.0 as you would expect, 
but then rails (specifically actionpack) tries to load an older rack 
such as 1.0.1 on top of it. So rubygems cries foul and the app fails to 
start.

I believe this is best seen as an issue with rails, so I opened a ticket 
here:

I had the same issue and am running Ruby 1.9.1 after updating rack to 
1.1.0.
I reloaded the rails v2.3.5 gem into the rubygems for my ruby version.
cd to rails app
thin start
works just fine with rack 1.1.0, rails 2.3.5 and thin 1.2.5

evidently a the rails adapter is updated when the rails gems in 
reinstalled.
