No such file to load -- yaml (LoadError)

Hello

I am trying to migrate my ruby from old server to new server.

I did a copy of all the binaries and have set all the relevant patch.
However I am not sure what I am missing. Below require works completely
fine on my old server. however , does not work fine in new server.

How can I know where is the yaml file located on the old server and any
advise how to fix this issue.

File Content:
require 'yaml'
puts "Test"

test.rb:1:in `require': no such file to load -- yaml (LoadError)

Thanks for your reply

ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [x86_64-linux]

gem -v
1.0.1

I copied entire binary from old machine to new one, so assume all is
good.

I tried to do gem install yaml

This is not a good idea. In Linux, rarely is the entire program in one binary. It is also linked to shared libraries on the system, like zlib.

Besides, as you can see you are using a version of Ruby from 2007 and an equally ancient version of rubygems.

Unless the new machine is also running software from 2007, I recommend reinstalling Ruby properly via RVM, compiling from source, or using your system's package manager.

YAML is not a gem but part of the standard library.

Unless you have a *very* good reason to use 1.8.6
you definitely should upgrade (at least to 1.9.3).

gem -v
1.0.1

You copied only the binary?
Then I assume your complete standard library is missing.

Try

   ruby -e 'p $LOAD_PATH'

In one of these directories there should be a ton of .rb files,
you need those, too (and all the subdirectories).

BUT: I highly recommend to install a current version from scratch.
