$ rspec spec/ not working for me. please help

I am new to rails and this is stopping me. I am trying to run rspec spec/ and I get errors. Can anyone help me?

This is the code I am getting:

Use

sudo gem update rspec-rails

It looks like you have an older version of the rspec-rails gem installed. Try updating it (2.1.0 is the current version at the time of writing):

gem update rspec-rails

Updated following comments:

You will need to specify the name of one or more spec files or a directory containing your spec files. For example if your spec files are in a folder called spec then this will run them all:

rspec spec

In a Rails project using Bundler:

bundle exec rspec spec

For more info on the rspec command:

rspec -h

Maybe is late, but for the error:

Perhaps {:unless=>#<Proc:0x00000001005b7790@/Library/Ruby/Gems/1.8/gems/rspec-core-2.1.0/lib/rspec/core/configuration.rb:53>, :if=>#<Proc:0x00000001005b7970@/Library/Ruby/Gems/1.8/gems/rspec-core-2.1.0/lib/rspec/core/configuration.rb:52>} is excluding everything?

Like it says, a test wasn't found in your test_spec file. You should add an "it" expression with your test case.
