Question

我在当地尝试redis，使用

启动了redis服务器

"redis-server"

01 Feb 06:22:50 * Warning: no config file specified, using the default config. In order to specify a config file use 'redis-server /path/to/redis.conf'
01 Feb 06:22:50 - Server started, Redis version 1.000
01 Feb 06:22:50 - The server is now ready to accept connections on port 6379

但是当我尝试从rails c console访问redis时，我一直看到＆＃34; Redis :: CommandError：ERR未知命令＆＃34;，我不知道出了什么问题。这是版本兼容的问题吗？

irb(main):009:0> redis = Redis.new(host: 'localhost', port: 6379)

irb(main):008:0* redis.get "1"
