Hi -
I’m new to Ruby/gems, etc. I wanted to put autocompletion on my irb. I
discovered http://eigenclass.org/hiki/fastri and followed directions (or
thought I did) to install the fastri gem. The problem is that I keep
getting the following error when I execute fastri-server. Client/server
are both on my local machine:
fastri-server
internal:gem_prelude:249:in push_gem_version_on_load_path': undefined method <=>’ for nil:NilClass (NoMethodError)
from internal:gem_prelude:14:in gem' from /home/eric/.gem/ruby/1.9.1/bin/fastri-server:18:in ’
If I try to run fri I also get…
fri
internal:gem_prelude:249:in push_gem_version_on_load_path': undefined method <=>’ for nil:NilClass (NoMethodError)
from internal:gem_prelude:14:in gem' from /home/eric/.gem/ruby/1.9.1/bin/fri:18:in ’
It seems the problem may be consistent with trying to run any gem.
I’m running Ubuntu 8.10 (intrepid)
Results of some attempts to solve the problem below…

I’ve gone as far as to download ruby-1.9.1-p0 then ./configure, make,
make install route but at this point I’m spinning my wheels. If anyone
has any ideas I’d sure love to hear. Thanks very much…
