activesupport ruby​​ 1.91 和 rake 的问题

Question

我安装了 ruby​​ 1.9.1

ruby​​ 1.9.1p378 (2010-01-10 修订版 26273) [i386-mingw32]

当我尝试运行 rake 任务时出现错误：

任何建议将不胜感激。

问题不在于 ActiveSupport。它出现在堆栈跟踪中只是因为它覆盖了内置的 Kernel#require 方法。

文件“Cms3/tools/rake/tasks.rb”在第 4 行有 require 'ftools'，但 ftools 是 在 Ruby 1.9 中已弃用。修改这些任务以使用 fileutils 代替，您就可以开始了。
