running spork after gem install spork rails

[chapmanf16]

After installing spork-rails I get this error when running 'spork':

Andrews-Mac-Pro-4:lb_final chapmanf16$ spork
/Users/chapmanf16/.rvm/gems/ruby-2.0.0-p247/bin/spork:23:in load': cannot load such file -- /Users/chapmanf16/.rvm/gems/ruby-2.0.0-p247/gems/spork-1.0.0rc3/bin/spork (LoadError) from /Users/chapmanf16/.rvm/gems/ruby-2.0.0-p247/bin/spork:23:in

If I run 'sudo spork' none of my gems are being located. I will get the following errors:

Using RSpec, Rails
Preloading Rails environment
Could not find actionpack-4.0.0 in any of the sources

It literally can't find any of them. I have only started learning ruby/rails for the past 3 days so I'm completely out of my element, but I am really not sure what to do. Any help would be appreciated.

Thanks.
