I’ve posted a different question just before – but before I can try  
and get a better idea of my error message, I was trying to start my  
application and ran into other problems.  
My application was developed last year in rails 1.2.3. I since  
upgraded my computer and have the latest version of rails. When I  
tried to star the application I got the following error message:

/…/config/environment.rb:62: undefined method `require_gem' for main:Object (NoMethodError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in`gem\_original\_require’

my environment.rb: 62 has:  
require\_gem ‘acts\_as\_taggable’  
which I know isn’t compatible

Would anyone have a suggestion on how to solve this?

Thanks  
Elle

Hi elle,  
require\_gem method has been deprecated. use simply ‘require’.

Thanks,

Changing it to ‘require’ I now get the following error message:

/usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem_original_require': no such file to load -- acts_as_taggable (MissingSourceFile) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in`require’  
…

I did install the gem. Should I install/update it?  
Thanks,  
Elle

Actually require\_gem should be replaced with gem
