I cannot install any gems and keep on getting the following error. ERROR: Error installing rails: invalid gem format for /usr/lib/ruby/gems/1.8/cache/ activerecord-2.0.2.gem I have tried updating rubygems, manually installing rubygems (not using synaptic) and still cannot get ruby gems to work. It would be great if anybody could give me a hand. Thanks
