【问题描述】：
我刚刚发布了 ginjo-rfm gem 的 v2.0.0。当我在库存的 Snow Leopard 机器（rubygems 版本 1.3.5）上安装这个 gem 时，我收到以下错误：
admin$ sudo gem install ginjo-rfm --no-rdoc --no-ri
ERROR: Error installing ginjo-rfm:
multi_json requires RubyGems version >= 1.3.6
但是，gem 安装并运行成功。
我只有一个运行时依赖项：ActiveSupport >= 2.3.5，并且它已经安装在我的所有机器上。在我的 gem 中，我什至没有提到 multi_json。
更奇怪的是，当我尝试在 Ubuntu 8.10（rubygems 版本 1.3.5）上安装 ginjo-rfm 时，rubygems 会引发缓冲区溢出错误（见下文）。
我的宝石有什么问题？这是一个相当简单的 gem & gemspec。我已经梳理过了，找不到任何会导致此类错误的问题。
如果有人想看看原始宝石：
mkdir ginjo; cd ginjo
gem fetch ginjo-rfm
tar -xf ginjo-rfm-2.0.0.gem
或者，在“元数据”文件中查看嵌入为 yaml 的 gemspec（见下文）。
谢谢！
缓冲区溢出错误
~$ sudo gem install ginjo-rfm --no-rdoc --no-ri

【问题讨论】：
-
多 json 依赖可能来自主动支持（我认为是 >= 3.1 版本）
-
我也是这么想的。但是我不明白为什么当我已经安装了 ActiveSupport 2.3.5 时它会绊倒我。我想知道我的 gemspec 是否有问题导致 rubygems 跳过已安装的 ActiveSupport，而是寻找 v3.1。
-
呃，这似乎不是依赖问题，或者至少不是列出的 gemspec 依赖的问题。我从 gemspec 中删除了所有依赖项，但在 Snow Leopard 上仍然出现 multi_json 错误，在 Ubuntu 8.10 上仍然出现缓冲区溢出错误。所以......我的gem的代码中一定有问题。 rubygems 是否真的在安装过程中加载了 gem？
-
我一定是疯了。我再次从 ginjo-rfm 的测试副本中删除了 activesupport 依赖项，现在 gem 安装错误已经停止。作为使用旧版本的 rubygems 和 activesupport 的陷阱，我将放弃这一点。
