Lock method does not work

[RafaelAcostaQ2]

Hi,
I'm not sure what am I doing wrong but I haven't being able to use this package. It is exactly what I need but for some reason it throws an error when I try to lock a resource.

redis_version:2.4.10

python version 3.5.2

This is my code

from redlock import Redlock
dlm = Redlock([{"host": "REDIS_SERVER_IP", "port": 6379, "db": 0}, ])

Acquire lock for 1 minute

my_lock = dlm.lock("this_is_my_key",1000)

ERROR:root:Error unlocking resource this_is_my_key in server StrictRedis<ConnectionPool<Connection<host=X.X.X.X,port=6379,db=0>>>
Traceback (most recent call last):

response = connection.read_response()
File "/home/redis/apps/Proj/env/lib/python3.5/site-packages/redis/connection.py", line 582, in read_response
raise response
redis.exceptions.ResponseError: unknown command 'EVAL'

Thanks in advanced!

Hi my english is not very well.
It seems the version of your redis server is too low you should update it to v2.6.0 or later.EVAL command

Can this result in a different raised exception? Something to the tune of your version of redis-server is too old?
