[chef] knife ssh cannot load such file -- readline (LoadError)

[Arthur Kalmenson < >]

Hello everyone,

I was listening to the latest Food Fight podcast (enjoy it, btw) and they were talking about knife ssh. I haven't really looked at it yet, so I figured now was a good time. However, as soon as I ran any knife ssh command, I got this:

$ knife ssh "role:experimental" "uptime"           

/home/arthur/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- readline (LoadError)

from /home/arthur/.rvm/gems/ruby-1.9.3-p125/bin/knife:19:in `<main>'

I thought it might have to do with using the latest ruby 1.9.3, so I tried it out in 1.9.2 but I got the same error. Google doesn't really give me much here, so I'm wondering if any has seen this before. Thanks!

All the best,
