The above answer is correct. You need to update Redis. If you're on mac, follow these steps to quickly update Redis:

  1. go to http://redis.io/download and download the latest version
  2. unpack it and go to that folder in the console
  3. $ make
  4. $ make install

And if you have an older version of Redis running at the moment, kill it:

  1. $ ps -ef | grep redis, the PID is the 2nd number on the 1st row
  2. sudo kill <the PID>

That's it
