How do I require a specific version of a ruby gem?

Question

Specifically, the ruby-oci8 gem. I have both 1.0.7 and 2.0.4 installed. I want 1.0.7.

I can just require oci8, but I don\'t get the version I want.

Try the following syntax (instead of require):

require_gem 'RMagick' , '=1.10'
require_gem 'RMagick' , '>=1.10'
require_gem 'rake', '>=0.7.0', '<0.9.0'
