使用RVM gemsets的Padrino : uninitialized constant ActiveSupport::Deprecation

Question

我在尝试运行应用程序时遇到错误，甚至没有尝试做任何复杂的事情，只是让基本的东西运行……只是想知道是否有人可以给我任何关于如何调试它的指点。我怀疑这可能与RVM gemsets有关，但我不确定...

下面是我收到的错误消息：

我在我的项目的gemset中列出了activesupport3.2.1，所以我不完全确定它为什么会抱怨。任何关于正在发生的事情的提示都将不胜感激，这样我就可以在将来调试这类东西。

看起来像是宝石碰撞了。

1. 更新padrino至最新版本0.10.5 (或0.10.6.c)

gem install padrino --pre

• 尝试使用bundler的稳定版本

gem卸载bundler -a；gem安装bundler

• 编辑项目的gem文件，然后指向padrino 0.10.5或0.10.6.c
