Question

我正在尝试将我的应用从Rails 2.3.4升级到2.3.8 ..

我进入了environment.rb文件，并更改了

RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION

到

RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION

（我还需要做点什么吗？）

我正在使用 MySQL服务器版本：5.1.47

我没有使用捆绑包

我在OS X 10.6.6上运行

这是我的database.yml，它匹配我在2.3.8中创建的WORKING应用程序（而非升级）

development:
  adapter: mysql
  encoding: utf8
  reconnect: false
  database: _development
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

当我这样做时，我加载的任何页面都会产生相同的错误..通过尝试从数据库构建/检索模型可以实现同样的错误，错误是这样的：

>> Company.new

编辑：来自environment.rb的宝石列表

  config.gem "authlogic"
  config.gem "hpricot"
  config.gem "BlueCloth", :lib => 'bluecloth'
  config.gem "daemons"
  config.gem "gravtastic", :version => '2.2.0'
  config.gem "json"
  config.gem "ruby-rapleaf"
  config.gem "ar-extensions"
  config.gem "url_shortener"
  config.gem 'aws-s3', :version => '>= 0.6.2', :lib => 'aws/s3'
  config.gem 'paperclip', :version => '>= 2.3.1.1'
  config.gem 'omniauth'

这不是创业板，它实际上是一个插件。 ACL9现在有一个GEM，当我最初开始使用它时，我只能以插件形式找到它。所以，对于任何人来说......

我有ACL9插件v .11，Rails 2.3.4

升级到Rails 2.3.8并且必须安装ACL9 gem，目前版本为v.12

Rails从2.3.4升级到2.3.8
