This error comes up in Redhat Enterprise Linux Server 5.4 - 64 bit.
Linux rhl-64-tibbr5 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
There is also this error in the stack trace.
uninitialized constant Nokogiri::VERSION_INFO
More version details:
jruby-1.4.0RC1 ruby/gems/1.8/gems/activesupport-2.3.4
Any idea?
After wasting a few hours on this issue, we realized we didn't need nokogiri in our application. So we got it rid of it and these errors disappeared.
Note: these errors show up only on a 64 bit Linux machine ( like RHEL, Oracle Linux etc.,). We didn't see any errors with 32-bit operating systems ( both Win and Linux)
I faced similar errors when using Nokogiri with JRuby 1.4.0 (and higher). What turned out to be the problem was that the machine was 64-bit but the JRE that JRuby ended up using was 32-bit. Ensuring that JRuby was run using a 64-bit JRE on a 64-bit machine solved the issues for me.
Some specifics in this blog post.
