update_rubygems 抛出“Gem::Specification:Class (NoMethodError) 的未定义方法 `find_by_path'”

Question

我正在使用 Redmine 1.0.3，在访问它时，我从乘客那里收到以下错误：

错误信息：

“actionmailer”的未定义方法“名称”：字符串

异常类：

无方法错误

建议的修复（参见undefined method `name' for "actionmailer":String）不起作用：

# gem install rubygems-update -v 1.3.5

我的 Ruby 版本是 1.9.3，我的 Rails 版本是 2.3.5。

有谁知道如何解决这个问题？提前致谢！
