Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

23 Feb

This error may occur if your rails version is lesser than 2.3.11. If you are not ready to upgrade, simply include this line in the files, Rakefile, script/server, and config/environment.rb above the line where you initialize boot.rb

require ‘thread’

Or you can downgrade the rubygems update to match the lower version of rails, if your rubygems > 1.6.0, then downgrade,
gem update –system 1.5.3
