Question

我有一些使用SyncEnumerator的代码。正如您所看到的here，SyncEnumerator需要generator.rb。为了包含这个，这个插件的开发者需要'generator'。这适用于我之前的Rails安装，但由于我升级了OS X并重新安装了Rails，因此无法正常工作。现在，当我尝试安装我的宝石时，我得到：

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)

任何人都知道如何解决这个问题？

谢谢！

Answer 1

这个问题与Rails无关。 SyncEnumerator和Generator都是Ruby Core Library的一部分。你应该在Ruby 1.8.x中同时拥有它们。

你能发布完整的异常追踪吗？

修改

在Ruby 1.9中，已删除Generator库以支持Fibers。请参阅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有效。

Answer 2

1.9中的

是Enumerator :: Generator

或者您可以创建自己的文件 '发电机' 就是这样 Generator =枚举器

GL。 -r

Answer 3

我遇到了ruby 1.8的这个问题，发现我的问题是我需要'生成器'而且需要'generator.rb'来修改它。我相信这是因为rails与自己的Generator类冲突

Answer 4

SyncEnumerator已移至Ruby 1.9.x中的rexml/syncenumerato r，您可以通过执行require 'rexml/syncenumerator'

来使用它

Rails找不到生成器类
