redis: wrong number of arguments for 'set' command

redis: wrong number of arguments for ‘set’ command

百度之:
结果1(没用): list之类为空引起的 …

结果2: 升级redis 版本到2.6以上, 2.6以前不支持set命令.
不会热升级(todo再百度), 就直接换最新redis,到github redis-windows 去下载(redis官网只看到mac版本的) https://github.com/ServiceStack/redis-windows/blob/master/downloads/redis-64.3.0.503.zip
