I had ruby 2.0 with rspec 3.0. I removed all rspec 3.0 gems and replaced them with 2.0. I did this to get rid of obsolescence warnings. Now my specifications do not work. I get the error below. What says the error and how can I fix it? None of the posts in this was helpful.

Ok, I found a fix.
I just removed all the unnecessary gems using
for i in `gem list --no-versions`; do gem uninstall -aIx $i; done
Then I just reinstalled rspec with the help gem install rspecthat rspec 3.0 gave me and fixed all the problems. But again, I receive warnings of failure.
Please tell me why the error occurred. The textbook author said that it should work with rspec 2.10.0 or higher.
