I just tried to boot up my app's console and it seems either something is broken or I've done something wrong? Here's what I'm doing.. First i cd to my project then run the command 'script/console development' only to get the following error: Loading development environment. /usr/lib/ruby/1.8/irb/completion.rb:10:in `require': No such file to load -- readline (LoadError) from /usr/lib/ruby/1.8/irb/completion.rb:10 from /usr/lib/ruby/1.8/irb/init.rb:218:in `require' from /usr/lib/ruby/1.8/irb/init.rb:218:in `load_modules' from /usr/lib/ruby/1.8/irb/init.rb:216:in `each' from /usr/lib/ruby/1.8/irb/init.rb:216:in `load_modules' from /usr/lib/ruby/1.8/irb/init.rb:21:in `setup' from /usr/lib/ruby/1.8/irb.rb:54:in `start' from /usr/bin/irb:13 Does anyone know what's going wrong and what could be done to fix it? Thanks for any help, Damien

Looks like you are missing the readline library. My Debian box has this package in Apt: libreadline-ruby1.8 - Readline interface for Ruby 1.8 The Windows installer seems to include readline by default. L

Im on OS X and when I was installing everything, readline was one of the first. I tried installing it again, but it seems to make no difference. I think somethings gone wrong with my install because i also installed lighttpd which has stopped working also. I can find anything online about un-installing everything and starting fresh and Im scarred that it's starting to look like doing a fresh install of my OS is going to be the only fix.. :(

You may consider installing ruby via fink or compiling from source. That would give you a new ruby environment to work with, without stressing about an OS rebuild.

Sorry. I meant Darwin Ports. Not fink.

If you have a bit of time you should try and figure out what happened before you reload in case it happens again. Sorry, I don't have an apple, so you may have to extrapolate what I do here. Can you start irb apart from the Rails console? If so, or if you can run another Ruby program, try a "puts $LOAD_PATH" and see where Ruby is searching. Here's how I search for the library in the filesystem on Linux: lesliev@mel:/usr/lib/ruby$ find -iname readline* ./1.8/i486-linux/readline.so So Ruby can load /usr/lib/ruby/1.8/i486-linux/readline.so because /usr/lib/ruby/1.8/i486-linux is in the $LOAD_PATH You can see what has actually been loaded with $LOADED_FEATURES - and you can get a list list of all these useful variables by calling "global_variables" - which I in turn found with "private_methods". Gotta love irb! (or I'm sure you could also read a good Ruby reference)
