Redis::CommandError: ERR wrong number of arguments for 'set' command

[leckylao]

on lib/redis.rb:658, it accepts options. But when I pass options it raise error.

  #   - `:ex => Fixnum`: Set the specified expire time, in seconds.
  #   - `:px => Fixnum`: Set the specified expire time, in milliseconds.
  #   - `:nx => true`: Only set the key if it does not already exist.
  #   - `:xx => true`: Only set the key if it already exist.
  # @return [String, Boolean] `"OK"` or true, false if `:nx => true` or `:xx => true`
  def set(key, value, options = {})

Steps:

Loading development environment (Rails 4.0.0)
irb(main):001:0> redis = Redis.new
=> #<Redis client v3.0.5 for redis://127.0.0.1:6379/0>
irb(main):002:0> redis.set "123", "123"
"[:set, \"123\", \"123\"]"
=> "OK"
irb(main):003:0> redis.set "123", "123", ex: 60
"[:set, \"123\", \"123\", \"EX\", 60]"
Redis::CommandError: ERR wrong number of arguments for 'set' command

The extra options to SET have been supported since Redis 2.6.12. Likely you're running an older version of Redis.

Pietern, you can see in the quote above that the user is running redis 3.0.6, not "an older version". There is an issue with the parameter paramater passing of &_boolify_set on line 673 of redis-rb/lib/redis.rb

Looking into this now myself since I'm blocking on it...

3.0.5 is the client version not Redis'.

True story! For anyone else who finds this thread, RedisToGo ships with 2.4.x by default :/

@jormon You can try @soveran and @cyx's http://openredis.com
