我的 Rails 环境遇到了一些问题 - 运行如下命令：

$ rails generate scaffold_controller model_name

导致以下跟踪：

    from script/rails:6:in `<main>'

由于跟踪中的任何内容似乎都来自我的特定项目，因此我对可能发生的事情感到有些困惑。如您所见，我在 rvm 安装的 ruby​​ 1.9.3 上运行 rails 3.2.13。

有任何想法吗？

我有同样的问题。事实证明，我的代码中某处有以下行。

include Term::ANSIColor

彩色术语输出需要此代码。但是当你需要生成或销毁脚手架时，可以暂时注释掉它。方法或符号 'clear' 与其他 gem 冲突。所以这可能也修复了 rake:erd。
