Heroku在Heroku上部署Rails gem

Question

我試圖在Heroku上部署我的第一個Rails應用程序。我正在使用設計進行身份驗證，但我的需求已更改，因此我將其刪除，現在正在使用巫術。

一切都是本地工作，但在部署時遷移我的數據庫，當我得到以下信息：

Running `rake db:migrate` attached to terminal... up, run.5220 
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/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/Rakefile:7)

我似乎無法找到任何剩餘提到設計的。刪除寶石後，有沒有人遇到這樣的問題？

謝謝！

您還需要刪除設計初始值設定程序文件/app/config/initializers/devise.rb。
