Hello, On all of my Rails 2.1.2 projects (released today), whenever I try to generate anything, I get the result “undefined method `empty?’ for /\_generator$/:Regexp”. Example: mbp15:~\> rails -v Rails 2.1.2 mbp15:~\> rails ./example create … … mbp15:~\> cd example mbp15:~/example\> ./script/generate model my\_model name:string undefined method `empty?' for /_generator$/:Regexp mbp15:~/example> ./script/generate migration my_first_migration undefined method`empty?’ for /\_generator$/:Regexp mbp15:~/example\> Any thoughts? Anyone else experiencing this? Thanks, -Jason ---

Installed the latest version of Ruby Enterprise Edition (though normal Ruby would probably work too) and everything is fine now. I think I had a patched version leftover from a security issue that arose earlier this summer, and the latest version of Rails didn’t like it so much. Cheers, -Jason ---

BTW, Google already indexed this: [http://rails.lighthouseapp.com/projects/8994/tickets/1259-bug-in-edge-rails](http://rails.lighthouseapp.com/projects/8994/tickets/1259-bug-in-edge-rails) Thought I might post it here in case someone finds a solution and posts it over there. ---

I’m having the same problem. I’m on a Gentoo box with Ruby 1.8.6 and all the latest patches. Pratik’s suggestion did nothing (actually my rubygems was already up-to-date). I’m downgrading to 2.1.1 if no quick solution comes up soon. ---

My bad. I didn’t provide the complete update instructions : [lifo@null ~]$ sudo gem update --system [lifo@null ~]$ sudo update\_rubygems On Fri, Oct 24, 2008 at 5:34 AM, Pilaf [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > > all the latest patches.
