我試圖將我的Rails應用程序升級到3.2.0.rc2，但是當我嘗試做一個rake db:migrate --trace我現在得到以下錯誤信息：不知道如何構建任務'db：migrate'w/Rails 3.2.0.rc2
DEPRECATION WARNING: The InstanceMethods module inside ActiveSupport::Concern will be no longer included automatically. Please define instance methods directly in ActionController::Base instead. (called from <top (required)> at /Users/Kyle/Desktop/skateparks-web/config/application.rb:4)

棄用警告似乎是在application.rb關於這一行：
Bundler.require(:default, :assets, Rails.env) if defined?(Bundler)
難道這被刪除或Rails的最新版本改變了嗎？我嘗試刪除這一行，然後再次運行遷移。然後我不再收到警告，但仍然得到Don't know how to build task 'db:migrate'錯誤。有任何想法嗎？
做一個bundle exec rake -T產生如下：

更新了我的問題w /輸出。看起來所有的'rake db'任務都沒有了。 – 2012-01-15 19:36:54
你是否在你的application.rb中做了'require'rails/all''，或者你正在加載一個子集？ – 2012-01-15 19:38:36
