Can I get multiple applications with different rails versions running on one machine?(can't activat

Rails
1

I did so, details below:
original:
gem 1.2.0
rails 2.0.2
one application(call it OLD) running well
now:
gem 1.3.1(for rails 2.3.2’s needs)
rails 2.0.2, 2.3.2(both exists)
another application(just a test application, almost blank, call it
NEW) meet errors:

/usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:149:in `activate’:
can’t activate activerecord (= 2.0.2, runtime),
already activated activerecord-2.3.2 (Gem::Exception)

Notice: I can’t run gem cleanup, and I don’t want change any of OLD
(including rake rails:freeze:edge RELEASE=2.0.2)
so I just freeze New, but still get errors.
Can anyone help me ? Thanks a lot!

Have you tried to freeze rails into the project?

Does the environment.rb file on OLD contain the correct
RAILS_GEM_VERSION?

Got it!
<1> cp /PATH/TO/ACTIVERECORD2.0.2/…/oci_adapter.rb /PATH/TO/
ACTIVERECORD2.3.2/…/oci_apapter.rb
<2>cp /PATH/TO/ACTIVERECORD2.0.2/…/oci_adapter.rb /PATH/TO/VENDER/
ACTIVERECORD2.3.2/…/oci_apapter.rb
And all works well~~~

OLD just run well.
I think it’s because the oci adapter, I install it with activerecord
2.0.2.
I will try to install a new one with activerecord 2.3.2, hope both of
them can coexist.
Thanks~
