I was recently using the latest version of rails, until I found out  
that the book I was using required an older version. I uninstalled my  
other versions and installed rails 1.2.6, however, I get the following  
message when I try to create a project:

me@darkstar:~$ rails proj  
can’t convert Enumerator into Array

Here is some info:

me@darkstar:~$ rails -v  
Rails 1.2.6  
me@darkstar:~$ ruby -v  
ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]  
me@darkstar:~$ gem -v  
1.3.5

Is there a different version of ruby or gem I should be running for  
rails 1.2.6? What could be the problem? What other info should I  
provide?

Thanks!

The first version of rails that was compatible with ruby 1.9 was rails  
2.3 so you’re quite a few versions behind. You could install ruby  
1.8.4, as I definitely remember using that version of ruby with rails  
1.x, but you should probably look at acquiring a book that isn’t  
several years out of date as a lot of things in rails have changed  
since then.

Is there a specific version of rubygems I should install with rails  
1.8.4?

(The book I’m using is Wrox’s Beginning Ruby on Rails. I’m using this  
book because it has exercises in it. If you know of a more recent  
book that has exercises in it, that would be great.)
