I’m hoping someone can help me out here. My application works fine  
locally using webrick. One I upload to my shared server space I get an  
application error saying rails has failed to start.

The log file production.log reads as follows:

MissingSourceFile (no such file to load – login\_system):  
/usr/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:21:in

/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/dispatcher.rb:37:in  
`dispatch’  
dispatch.cgi:10

The tutorial I followed to set up the login system is here…  
[http://wiki.rubyonrails.com/rails/pages/HowToQuicklyDoAuthenticationWithLoginGenerator](http://wiki.rubyonrails.com/rails/pages/HowToQuicklyDoAuthenticationWithLoginGenerator)

I’ve got my host to install the login\_generator gem using: ‘gem  
install login\_generator’ unfortunately it made no difference.

I am really stuck as to why this isn’t working, if anyone can offer  
any pointers if would be greatly appreciated.

Thanks,  
Paul.

Hi,  
are you sure you copied this file login\_system.rb to your host? it’s  
probably in the lib directory. you don’t need the generator gem on the  
host to get this running.

wow that was an easy fix! thanks for that.

However, when I try to log in I get the following error… any ideas  
what this is all about?
