I am trying to use memcache-client to store session. I have found great  
instructions online. However, I keep getting error and fail to start  
rails on radrails.

I have “gem install memcache-client”:

# ============ gem list =============== memcache-client (1.3.0) A Ruby memcached client

I’ve configured with the following:

# =========== environment.rb =============== require\_gem ‘memcache-client’ Rails::Initializer.run do |config| config.action\_controller.session\_store =:mem\_cache\_store end memcache\_options = { :compression =\> true, :debug =\> false, :namespace =\> “pr-#{RAILS\_ENV}”, :readonly =\> false, :urlencode =\> false } memcache\_servers = [‘127.0.0.1:11211’] CACHE = MemCache.new(memcache\_options) CACHE.servers = memcache\_servers ActionController::Base.session\_options[:cache] = CACHE

I keep getting either of these errors (depending on whichever one comes  
first in environment.rb:

=========== errors ===============  
uninitialized constant CGI::Session::MemCacheStore (NameError)

# uninitialized constant MemCache (NameError)

memcache-client appears to have loaded properly with require\_gem. I  
tried changing the config many times, but keep getting these errors.  
Any help would be greatly appreciated.

thanks a lot!

This is due to not having at least “hoe” and maybe “rubyforge” gems not  
also updated.

Just do a global update if you don’t have any others, but otherwise just  
try going into irb and directly including the memcache-client lib.

# irb

> require ‘rubygems’  
> gem ‘memcache-client’

You should get an error here about what’s missing.
