rackup无法加载activerecord

可能重复:
  Error loading Active Record gem with sinatra app using RVM

我有一个Faye应用程序,我想在其中使用ActiveRecord。我在我的faye.ru中有这个:

require "rubygems"
require "faye"
require "sqlite3"
require "activerecord"

... other code

我想通过以下方式启动它:rackup faye.ru -s thin -E production

此操作失败,并显示以下错误:/home/tempus/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in 'require': cannot load such file -- activerecord (LoadError)。如果我运行rvm current,我会得到:ruby-1.9.3-p125@pno。如果我在rvm目录上为这个gemset做了一个ls,我可以看到确实安装了activerecord:

actionmailer-3.2.2    builder-3.0.0              hike-1.2.1            polyglot-0.3.3   sprockets-2.1.2

arel-3.0.2            faye-websocket-0.4.4       multi_json-1.2.0      rdoc-3.12

我无法理解为什么会说它无法找到activerecord。有线索吗?

即使gem被称为activerecord,该类也被称为ActiveRecord,在蛇案例中转换为active_record

require 'active_record'
