IRB won't work

rubyonrails-talk
1

I am a newb. Running OS X leopard. Installed ruby, rails, mysql through macports. Everything works fine except today I tried to run the irb console. I get the following:

computer: mark$ ruby script/console Loading development environment (Rails 2.1.0) dyld: NSLinkModule() error dyld: Symbol not found: _rl_completion_matches   Referenced from: /usr/local/lib/ruby/1.8/powerpc-darwin9.4.0/ readline.bundle   Expected in: flat namespace

Trace/BPT trap

computer: mark$ ruby -v ruby 1.8.6 (2007-09-24 patchlevel 111) [powerpc-darwin9.4.0]

Any ideas?

OK.

Installed ruby, rails, mysql through macports.

Huh? If you're running Leopard, you should have ruby and rails already! You may have a conflict:

rab:Users/rab $ which ruby /usr/bin/ruby rab:Users/rab $ ruby -v ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]

rab:Users/rab $ which rails /usr/bin/rails rab:Users/rab $ rails -v Rails 2.1.0

Everything works fine except today I tried to run the irb console. I get the following:

computer: mark$ ruby script/console Loading development environment (Rails 2.1.0) dyld: NSLinkModule() error dyld: Symbol not found: _rl_completion_matches Referenced from: /usr/local/lib/ruby/1.8/powerpc-darwin9.4.0/ readline.bundle Expected in: flat namespace

Trace/BPT trap

computer: mark$ ruby -v ruby 1.8.6 (2007-09-24 patchlevel 111) [powerpc-darwin9.4.0]

Any ideas?

I hope that gives you a starting point.

All my responses are the same as yours. Just no irb. Can irb be reinstalled by itself or maybe I should just reinstall ruby again?
