I came back from holidays today to my capybara and selenium powered tests throwing this error:

Essentially, nothing changed before I left and these tests just work for other people (that is, other computers). In an effort to have them work again, I upgraded Firefox, I added some hostnames to my /etc/hosts to remove DNS lookups, upgraded all gems (including capybara). I'm running out of ideas.

The environment is OS X 10.9.5. I rebooted a couple of times just in case. I'm running Ruby 2.1.5, Rails 3.2.21, MiniTest 4.7.5.

Any other ideas to try?

gem install 'eventmachine'  -v 1.0.3

and if you have other than 1.0.3 version uninstall it and install the specified version.

May be,that solves the issue.
