Need help with 'cattr_accessor' ActiveRecord Error

Why am I getting this error from ActiveRecord? I have Ruby on Rails installed on my Mac Powerbook. I used the Hivelogic artilce as my installation guide and completed the installation without any errors. I have tried to install the latesst ActiveRecord gem, but when I run the locate cammand, it still references the old version of ActiveRecord.

/usr/local/lib/ruby/site_ruby/1.8/active_record/base.rb:246: undefined method `cattr_accessor' for ActiveRecord::Base:Class (NoMethodError)   from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
        from /usr/local/lib/ruby/site_ruby/1.8/active_record.rb:37
        from ./db.rb:1
        from script.rb:3

Any suggestions would be greatly appreciated.

Well, I don't know about the Hivelogic article. But once you have ruby and rubygems setup it should be all easyride.

try "gem list --local" to see what gems are installed.

Try uninstalling EVERYTHING. Then manually check that you have no traces of rails, or Active*ANYTHING installed.

Then do "gem install -y rails" which should bring you Rails + all the dependencies.

Your problem seems to be that your ActiveRecord is not installed as GEM but as a regular Ruby library.

it sits in /usr/local/lib/ruby/site_ruby/1.8/active_record/base.rb while it shoud be somewhere like /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb

 

this can happen if you manually compile it and do 'make install' equivalent. i.e. ruby install.rb or whatever. Don't do that! :-) Use gem.

Thanks for the reply.  

As you have probably already figured out. I'm new to the RoR game.   What's the command for uninstalling gems.

 Thanks Again,

 Jim

to see a list of installed gems: gem list --local

to remove a gem: gem uninstall GEMNAME (i.e. gem uninstall rails, gem uninstall activerecord etc)

how original :-)

Making progress.

 I've used the gem uninstall command to remove all my gems - I'm gemless.

Now how should I manually check for rails or active anything. If I run a locate command on rails or activerecord it appears they are both lurking on my computer.

Then once I get all of references off my computer, I should run  "gem install -y rails"

Again, I really appreciate you help. I've been banging my head on the wall on this for about a week.
