ActiveSupport uninitialized constant :: Cache :: MemCacheStore :: MemCache

I got this error when I started my project with memcache (gem) and rails 3.0.0beta p>

Here's the full trace:

Here is some code from my .rb environment, line # 5: Cache module

 require 'active_support/cache' module ActiveSupport module Cache class MemCacheStore < Store def logger Rails.logger end end end end

Is there anyone who can guess what is wrong here, is this a problem with rails 3?

in fact, you did not add the gem "memcache-client" to your Gemfile, apparently you only have a "memcache" gem

I think my answer is too late :) But maybe this helps someone. I have the same error and the problem was in the file name in the lib / memcache.rb directory. After renaming it, the project started as usual.
