module Imodule
  ???
end

class Some
  include Imodule

  def self.imethod
    puts "original"
  end
end

Some.imethod
# => "overrided"

如何创建一个覆盖静态方法的模块？

这是一个深入了解ruby功能的访谈问题.不建议另一个问题的表述:)

Rails 3.1.我正在尝试预编译资产.

$ rake assets:precompile RAILS_ENV=production
  rake aborted!
  /home/user/project/public/assets/jquery-ui.min-0e8a11c7e970b57b4bf5c449cb14480d.js.gz has a invalid UTF-8 byte sequence
  Tasks: TOP => assets:precompile

  (See full trace by running task with --trace)

有任何想法吗？

我已经安装了tesseract-ocr(0.1.5)宝石.

还安装了依赖项(tesseract/3.04.00和leptonica/1.72)

Mac OS X Yosemity.

当我rake db:migrate出现错误时出现:
