PDF prawnto不能与rails 3.2.8一起使用

Question

我们在rails 3应用程序中使用prawn来生成pdf文件。现在，在升级到rails 3.2.8之后，rails插件prawnto出现了一个问题。下面是错误：

DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them o
ut and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes

emclab-failed2/config/environment.rb:5)

D:/rails_proj/emclab-failed2/vendor/plugins/prawnto/lib/prawnto/template_handlers/base.rb:3:in `<module:TemplateHandlers>': uninitialized co
nstant ActionView::TemplateHandler (NameError)

甚至rails服务器都无法启动。有没有办法解决这个问题？谢谢。

对虾是一颗宝石，并不依赖于大虾与rails一起工作。这是一个由aniket编写的在Rails3.2中直接使用对虾的post。我们遵循了说明，它在rails 3.2.8中也能正常工作。如果你有与prawnto相同的兼容问题，请查看它。
