I tried to just change the rails gem I use with my application and I
got the following error:
/usr/local/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/
active_support/core_ext/module/aliasing.rb:33:in alias_method': undefined methodtemplate_exists?’ for class
`ActionController::Base’ (NameError)
I can create a new project and it starts fine. Where is this error
coming from? Are there certain steps to migrate from 2.2.2 to 2.3.2?
