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，我得到一个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

有没有人遇到过这个？有任何想法吗？

如果您的 redis 是 9.10 发行版提供的版本，则版本太旧而无法使用 2.x gem 运行。2.x gem 至少需要一个 1.2 redis
