Rails无法找到生成器类

我有一些使用SyncEnumerator的代码。正如你可以看到here，SyncEnumerator需要generator.rb。为了包含这个，这个插件的开发者需要'generator'。这对我以前的Rails安装起作用，但是因为我升级了OS X并重新安装了Rails，所以无法正常工作。现在，当我尝试安装我的宝石，我得到：Rails无法找到生成器类

Macintosh:mls TAmoyal$ sudo rake gems:install 
(in /Users/TAmoyal/Desktop/RoR_Projects/mls) 
rake aborted! 
no such file to load -- generator 

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

有谁知道如何解决这个问题？

谢谢！

该问题与Rails无关。 SyncEnumerator和Generator都是Ruby Core Library的一部分。你应该在Ruby 1.8.x中都有。

你能发布完整的异常跟踪吗？

编辑：

在Ruby 1.9发电机库已赞成纤维去除。见here和here。

您使用的库与Ruby 1.9不兼容。您可以尝试从Ruby 1.8.x复制Generator和SyncEnumerator文件，但我不知道此解决方案是否可行。

感谢澄清使用它。我有Ruby 1.9.x.堆栈跟踪已发布 – Tony 2009-06-26 22:43:02

在1.9有枚举::发电机

，或者您可能能够创建自己的文件 “发电机” 这只是没有发电机=枚举

GL脱身。 -r

我有这个问题与红宝石1.8，发现我的问题是，我需要'发电机'，并改变它需要'generator.rb'修复它。我相信这是因为与自己的发电机类轨冲突

SyncEnumerator已移动到红宝石1.9.x的rexml/syncenumerato R您可以通过做require 'rexml/syncenumerator'
