[Rails] `parse!': invalid option: --autotest (OptionParser::InvalidOption)

Well, here it is. I am learning Rails and rSpec at the same time
courtesy of
Michael H.'s tutorial. All was going good when this happened. rspec
is
woking on my other projects so I have no idea what I did wrong. I tryed
removing files one by one from ‘spec’ directory to see if one of the
files
was jacked up but I either get nothing or this same thing. Please help
if
you know what I did wrong.


When i run $ autotest, here is what I get back:

bundle exec /usr/local/bin/ruby -S

Looks like you’ve got rspec-core-2.0.1 and rspec-core-2.0.0.beta.18. I’d
recommend uninstalling the beta.

HTH,
