daemons load activesupport 2.2.2 instead of 2.1.0, causing failure


I have a couple of daemons that im trying to setup to be run for my
app. The environment load is as follows..

ENV["RAILS_ENV"] ||= "development"
require File.join(File.dirname(__FILE__), "/../../config/environment")

And the error I get is

#<LoadError: no such file to load -- active_support>
#<Gem::Exception: can't activate activesupport (= 2.1.0, runtime),
already activated activesupport-2.2.2>

I have activesupport 2.2.2, 2.1.0 and 1.4.4 installed and I think it
just loads the latest version available.
How do I force the daemon to load 2.1.0? I understand that in
production too, it loads the latest version of rails and all other
gems available. But I need it to use the versions I specify.

Any ideas at all on how to do this?

you can use gem 'some_gem', '=1.2.3' to force version 1.2.3 of the gem
some_gem to be loaded, or you can make sure that whatever is loading
activesupport without specifying a version tries to do so after the
thing that loads a specific version.


Hi Fred,

I did read about this solution elsewhere before starting this thread.
So i did

gem 'activesupport', '=2.1.0'
require 'activesupport'
require File.join(File.dirname(__FILE__), "/../../config/environment")

But then I got the errors

<LoadError: no such file to load -- active_support>
<Errno::ENOENT: No such file or directory - /Users/fire/Sites/Vinay/
<NameError: uninitialized constant Repeat> #Repeat being one of the
models of my app.

Im trying to uninstall activesupport 2.2.2 from my machine but not
getting anywhere with that either. Even if I DO manage that in my
local machine, in production, the daemon is still gonna trouble me by
loading the latest gem versions rt?

I honestly dont understand why or how but it started working when I

require File.dirname(__FILE__), "/../../config/environment"


require File.join(File.dirname(__FILE__), "/../../config/

There is one other problem now though. When the daemon is running, it
does not output anything to the log file. I can only see its progress
in the development log.
Once the daemon is stopped, it outputs some stuff and a few errors
which make no sense because the daemon runs successfully. (including
"No such file to load activesupport")

My daemon is called reminders_ctl and the log/reminders.rb.log is the
log file im looking into. How do I make it o/p to this log file so
that I can monitor the daemons progress from this one file?
