libxml-ruby failed to load at x86_64

Question

We are having problem with libxml-ruby gem at the server side Possible because it uses x86_64 architecture:

gem version 1.1.4

Reinstalling the gem doesn't help Can somebody suggest what to do?

Answer 1

Did this get resolved? I'm having a similar issue.

Answer 2

Hello, I had this exact same issue in a Centos....Aparently there is a problem with gem version 1.1.4 and 64 bit machines. Head over to rubyfourge and dowload version 1.1.3.

http://rubyforge.org/frs/?group_id=494

download the .gem an then just run:

gem install libxml-ruby-1.1.3.gem

On the console. I hope this helps
