*** Redis::CommandError Exception: ERR unknown command 'locked?'

[lbrito1]

The snippet in the docs for locked? does not work. I'm using version 0.2.7.

(byebug) redis = ::Redis.connect
#<Redis client v3.3.0 for redis://localhost:6379/0>
(byebug)  redis.locked?("test")
*** Redis::CommandError Exception: ERR unknown command 'locked?'

I have similar problem when using default gem source. After switching to github version the problem was solved.

Same here, had to switch to the github master branch to resolve this issue.
