Installing Rails 2.2

I was running
•  Rails 2 (ver. 2.0.2, I think)
•  Gem (ver. 1.0.1)

I upgraded to 2.2 with the following commands:
gem update –system
cd’d to the ruby-container directory
gem install rails
rails –v  (yielded: 2.2.0)
setenv -m rails_gem_version 2.2 (set the machine’s
“rails_gem_version”  to 2.2)
echo %rails_gem_version%   (yielded: 2.2)

I had a partial app I created under Rails 2 working. (Rails 2.0.2, I

Today,  I ran:
K:\_Projects\Ruby\_Rails_Apps\Payroll>ruby script/server

I got:
=> Booting Mongrel (use 'script/server webrick' to force WEBrick)
=> Rails 2.2.0 application starting on
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at
** Starting Rails with development environment...
lib/initializer.rb:514:in `send': undefined method

Possible mistakes I can think of:
1.  I installed Rails 2.2 instead of merely updating the existing
Rails 2.0.2
2.  gen –v produces 1.3.1 --- I don’t know if that’s a problem
3.  I created a machine’s environment variable “rails_gem_version”
and set it to 2.2
4. I change config/environment.rb alternately from RAILS_GEM_VERSION =
'2.0.2' unless defined? RAILS_GEM_VERSION to:
-- RAILS_GEM_VERSION = '2.2' unless defined? RAILS_GEM_VERSION
-- RAILS_GEM_VERSION = '2.2.0'

Thanks in advance for any ideas on what the problem may be,

cache_template_extensions was a deprecated setting and has since been

Hi Freddy and Frederick,

Thanks for you responses.  I see from the Github site that
cache_template_extensions has been deprecated.

An exhaustive search of rb/erb/rhtml files in my Ruby/Rails directory
reveals that "cache_template_extensions" appears only in the non-2.2
versions of some Rails components.

A search of my old Payroll app,  now renamed to Payroll-1, showed only
one instance of  "cache_template_extensions" containment in
Payroll-1\config\environments\development.rb.  Sounds like that's my
culprit. I commented it out.

Things are back to normal.  I wonder if I should expect any more
surprises.  Perhaps I should start from scratch with Rail 2.2.

Again thanks to both of you for your help.

Best wishes,
