Rails未初始化的常量ActiveSupport :: Autoload（NameError）？
我在Michael Hartl教程的第3章，我被困在测试部分。 最初它有一个未初始化的常量Rails（NameError）的问题，但在添加之后
require 'rspec/rails' require 'active_support' require 'active_support/deprecation' require 'activerecord-nulldb-adapter' 对于spec_helper.rb文件，uninitalised常量ActiveSupport :: Autoload（NameError）存在这个新问题。
