Hi!  
I installed Rails manually. Now it creates the app nicely but when i  
give  
any script/generate command, it halts with following error on command  
prompt  
./script/…/config/boot.rb:29: undefined method `gem' for main:Object (NoMethodError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require’  
from script/generate:2

I am on Windows Vista and installed each component of rails as a  
seperate  
gem in this order:

1. Activesupport [http://rubyforge.org/projects/activesupport/](http://rubyforge.org/projects/activesupport/)
2. Actionpack [http://rubyforge.org/projects/actionpack/](http://rubyforge.org/projects/actionpack/)
3. Actionmailer [http://3.postersgalaxy.com/](http://3.postersgalaxy.com/)
4. Activerecord [http://rubyforge.org/projects/activerecord/](http://rubyforge.org/projects/activerecord/)
5. Actionwebservice [http://rubyforge.org/projects/aws/](http://rubyforge.org/projects/aws/)
6. Rake [http://11.mimbarminang.com/](http://11.mimbarminang.com/)
7. Rails [http://rubyforge.org/projects/rails/](http://rubyforge.org/projects/rails/)

What could be wrong.

Thanks and regards,  
Swanand
