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/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:inrequire’

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!

When you built Ruby you didn't have the readline headers installed, so
it didn't link against them.
Rebuild ruby with the readline packages (incl. headers) installed.

Thanks AJ. I'm using knife on an Ubuntu machine, so I'm not sure where the
readline package is. I've installed chef on my workstation with RVM, so
perhaps I'm missing the readline header because of that?
Following this guide:
http://assets.en.oreilly.com/1/event/61/oscon2011_tute_chef_19882.htm, I
have all the correct libraries installed... Any ideas what the issue might
be?

Hi Arthur,
To check if you have the readline's headers installed try this:
$ dpkg -l | grep libreadline.*-dev
If they are already installed you should get something like this:
ii libreadline6-dev 6.2-2ubuntu1 GNU readline and history
libraries, development files
If you don't get anything means you don't have it, so install them by doing:
$ sudo apt-get install libreadline-dev
I hope this helps.
Greetings

Thanks Juan. Installing libreadline-dev worked great.
