Hi,

I’ve got a Rails 2.2.2 app and I’m trying to get BackgrounDRb running.  
I’m just following the simple example in Advanced Rails Recipes.

I installed BackgrounDRb from Git,  
installed the packet and chronic gems,  
ran ‘rake backgroundrb:setup’,  
generated a worker,  
and then tried to run ‘script/backgroundrb start’  
but I get:

/vendor/rails/actionpack/lib/action\_controller/base.rb:1276: undefined  
method `deprecate' for ActionController::Base:Class (NoMethodError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`gem\_original\_require’  
from  
/usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`require' from /Users/macmini/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:156:in`require’  
from

`gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’  
… 14 levels…  
from  
/Users/macmini/.gem/ruby/1.8/gems/activesupport-2.3.2/lib/active\_support/dependencies.rb:156:in  
`require' from /Users/macmini/Projects/Git/shopseen/vendor/plugins/backgroundrb/lib/backgroundrb/bdrb_start_stop.rb:90:in`start\_bdrb’  
from  
/Users/macmini/Projects/Git/shopseen/vendor/plugins/backgroundrb/lib/backgroundrb/bdrb\_start\_stop.rb:16:in  
`start’  
from script/backgroundrb:23

Any suggestions? Also, how do I get the console to spit out the full  
trace and not skip 14 levels?

Thanks.

Doesn’t look like a 2.2.2 app. Seems you might be at 2.3.2. As you  
have frozen Rails into vendor, you can back up and freeze a 2.2.2  
version in its place (assuming you don’t depend on any of the cool 2.3  
features yet).

Yup the problem was because of vendored rails gem. You can pull again  
from  
backgroundrb repository and it should work alright.
