ruby on rails - activesupport-2.3.11 conflicts with activesupport (>= 3.0) -


i working on ruby on rails project former programmer created. old code, using ruby 1.8.7 , rails 2.3.*. not going upgrade versions because need add few features , don't want break (and i'm totally new ruby on rails development, i'm doing 1 project). getting error:

actionview::templateerror (unable activate climate_control-0.0.3, because activesupport-2.3.11 conflicts activesupport (>= 3.0).

what need fix this? thanks!

according climate_control gemspec file, version trying run requires activesupport 3+, rails 3.

looking through commit history, appear gem ever released rails 2, think you're either going have upgrade rails, or remove gem.
