Re: [Backgroundrb-devel] error starting backgroundrb

Thu, 23 Oct 2008 16:43:32 -0700 

Hi Hemant
This is a fresh new application with no code in it except the small code i made to test backgroundrb. as you have actually pointed out i did run a $: on the console and lib was there but no lib/workers (with s). so that could be the reason but why is it not there and how can i add it ?

Were you upgrading from old version or fresh install?

Try to reproduce the problem with a fresh rails application and send
me the zipped copy, if it still doesn't work.

Afaik, looks like "lib/workers" is not in path. Are you using
config.pluigns directive in your rails application?

somewhere i read that this can be fixed by rolling back the packet  
gem to
version 0.1.5. it did fix the start up problem but then when i call  
a worker
from the console i get the following error which i guess has to do  
with the

dependency.
