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里有这个:
require "rubygems"
require "faye"
require "sqlite3"
require "activerecord"
... other code我想从:rackup faye.ru -s thin -E production开始
如果出现以下错误,就会失败:/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,我得到:ruby-1.9.3-p125@pno。如果我为这个see集在rvm dir上执行ls,我可以看到activerecord确实安装了:

即使gem被称为activerecord,这个类也被称为ActiveRecord,它在蛇的情况下转换为active_record:
require 'active_record'https://stackoverflow.com/questions/9890525
