由于追踪中似乎没有任何东西来自我的特定项目，我对可能发生的事情感到有点困惑。如您所见，我在安装了rvm的ruby 1.9.3上运行rails 3.2.13

有什么想法吗？

我也有同样的问题。事实证明，我的代码中有下面这行代码

include Term::ANSIColor

彩色术语输出需要此代码。但是，当您需要生成或销毁脚手架时，可以暂时将其注释掉。方法或符号“清除”与其他宝石冲突。因此，这可能也修复了rake:erd。

我在使用Rails 4.0.0并通过宙斯运行生成器时遇到了相同的错误。我已经定制了一些生成器（默认情况下关闭了helpers/stylesheets/javascripts），但除此之外，所有这些都非常普通。你解决过这个问题吗？很遗憾，没有。。。我只是通过避免受影响的发电机来解决这个问题……啊，好吧。下周我打算花点时间看一下。我会在这里发布任何有用的东西。
