Exception encountered: #<NameError: uninitialized constant RSpec::Core::CommandLine>

Do let me know, if necessary, the correct Github repo I should post this issue in.

GEM VERSIONS
Rails 4.2.0
ruby 1.9.3p547 (2014-05-14) [x86_64-linux]
rspec-core (3.1.7)
guard (2.11.1)
guard-compat (1.2.0)
guard-spork (2.1.0)
spork (1.0.0rc4)
spork-rails (4.0.0)
spork-testunit (0.0.8)

I have not used RSpec since December, when our app was still Rails 3. Since, we've upgraded to Rails 4 and updated the necessary gems. I have not changed anything in the Guardfile, .rspec, or spec/spec_helper.rb files yet.

When I run bundle exec guard like I used to, I receive no error (except for Rails-specific deprecation warnings). When I switch to another tab in my terminal, I run bundle exec rspec spec/features/admin/login_spec.rb. As noted in the title, I receive the following error/backtrace:

Exception encountered: #<NameError: uninitialized constant RSpec::Core::CommandLine>

If I need to add gists of additional files, let me know. I think this issue relates to the fact we upgraded to Rails 4. I am not sure where (maybe Spork), but a README listed that it covered <= 4.0.0, not Rails 4.2.0

@mattmartini I am no longer using guard-spork. Feel free to close this issue.
