取出導軌從項目

Question

插件，我讓我的鐵軌此棄用錯誤3.2項目，我從一個軌道3.1項目升級：

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 out 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 for more on this: http://weblog.rubyonrails.org/2012/01/04/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/Rakefile:7) 

我試圖擺脫這種錯誤的，但我可以似乎找不到插件。我已經從供應商/插件中刪除了該插件。

Answer 1

如果你的供應商/插件是完全空的，那麼我敢打賭你正在部署到Heroku。作爲部署過程的一部分，Heroku將插件注入到您的應用程序中。查看this Stackoverflow answer以獲得對此問題的實際Heroku響應。
