Having trouble setting up Redis for ruby.

Question

I am trying to play with redis on my Ubuntu machine and my little script doesn't work. I have installed redis gem and tried this little script (I know its pretty small)

require 'redis'
redis = Redis.new

I get this error :

./redis.rb:4: uninitialized constant Redis (NameError)
from redis.rb:2:in `require'
from redis.rb:2

when I comment the line 2, I dont get any problem. How come the class Redis is not recognized?

Answer 1

Rename your file to something other than "redis.rb" (try test.rb), and make sure you require rubygems.

require "rubygems"
require "redis"

redis = Redis.new
