[BUG] Segmentation fault ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

[delta force]

I am using Active Record outside rails. I created one rb file at:

/usr/share/puppet-dashboard/bin/process.rb


Code of process.rb

#!/usr/bin/ruby

require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter => "mysql2",
:host => "localhost",
:username => "root",
:password => "root123",
:database => "testproject_development"
)

But when i run this rb file then i get the following error:-

/usr/local/rvm/gems/ruby-1.9.3-p362@artwork_auto/gems/json-1.7.7/lib/json/ext/parser.so:
[BUG] Segmentation fault ruby 1.8.7 (2011-06-30 patchlevel 352)
[x86_64-linux]

Any help will be highly appreciated.

You've got some sort of ruby version mixup here - you've got ruby 1.8.7 that is trying to load a native extension compiled for ruby 1.9. I'd guess that is because your shebang is saying use /usr/bin/ruby, which is presumably the system provided ruby, but dvm has setup the environment variables that ruby uses to have it look for gems in the rvm copy of ruby.

I assume that you can't change the way it is invoked (to ruby process.rb rather than ./process.rb) but if you change the shebang to 

#!/usr/bin/env ruby

that should pick up the rvm provided ruby, assuming that this script is running in a context where rvm has been loaded.
