Question

环境：

Ubuntu 9.10（在VirtualBox中运行）
Ruby v1.8.7
Redis gem v2.0.6

在irb上，当我尝试初始化Redis时，我得到RuntimeError。这是一个片段：

irb(main):001:0> require 'rubygems'
=> true

irb(main):002:0> require 'redis'
WARNING: using the built-in Timeout class which is known to have issues when used for opening connections. Install the SystemTimer gem if you want to make sure the Redis client will not hang.
=> true

irb(main):003:0> r = Redis.new

以前有人碰到过吗？有什么想法吗？

Answer 1

如果您的redis是9.10发行版提供的版本，则该版本太旧而无法与2.x gem一起运行。 2.x宝石期望至少1.2 redis

RuntimeError：-ERR Unknown在Ruby上运行redis gem的命令
