An error occurs when I execute this command:

c:\gem install state_machines

ERROR: While executing gem ... (Errno::EINVAL) Invalid argument - c:/Ruby193/lib/ruby/gems/1.9.1/gems/state_machines-0.2.2/test/unit/node_collection/node_collection_after_being_copied_test

This fixed my problem:

git clone https://github.com/jeff-hamm/state_machines

cd state_machines

bundle gem state_machines

rake install
