Hi, I am having a problem that I've not seen before and would appreciate some help in debugging. When I try to start irb, I get the following error: vadai:~ ppk$ irb /Library/Ruby/Site/1.8/rubygems/custom\_require.rb:27:in `gem\_original\_require': no such file to load -- config/environment.rb (LoadError)   from /Library/Ruby/Site/1.8/rubygems/custom\_require.rb:27:in `require'   from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/irb/init.rb:253:in `load\_modules'   from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/irb/init.rb:251:in `each'   from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/irb/init.rb:251:in `load\_modules'   from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/irb/init.rb:21:in `setup'   from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/irb.rb:54:in `start'   from /usr/bin/irb:13 Any help would be appreciated.

I still haven't solved the problem, but I noticed that when I type in the full path to irb at the shell prompt, /usr/bin/irb, I don't have this problem. It just starts up fine. If I type "irb" then I get this problem. Any suggestions? Thanks. > **···** > > -- > Posted via [http://www.ruby-forum.com/](http://www.ruby-forum.com/). ---

% which irb it'll prolly answer /usr/local/bin/irb or somesuch... that means you've got multiple installs of ruby on your system and neither has a customized suffix (like ruby19 or ruby187). I recommend against that. Consider nuking your second install and reinstalling with --suffix passed to configure. > **···** > > On Aug 26, 2008, at 10:37 , Pravin Kumar wrote: > > > I still haven't solved the problem, but I noticed that when I type in > > the full path to irb at the shell prompt, /usr/bin/irb, I don't have > > this problem.
