我在 OSX 上的 Ruby 2.0.0 (rvm)下运行Rails 3.2.14。当我尝试访问大多数方法的 ri 文档时，我得到以下堆栈跟踪。
堆栈跟踪：

我认为问题与默认为RDoc 4.0的 Ruby 2 有关，而由于依赖关系，捆绑程序环境正在使用RDoc 3.12.2 ：
journey-1.0.4 depends on rdoc (~> 3.11, development)
journey-1.0.4 depends on rdoc (~> 3.10, development)
tilt-1.4.1 depends on rdoc (>= 0, development)
tilt-1.4.1 depends on rdoc (>= 0, development)
mail-2.5.4 depends on rdoc (>= 0, development)
rdoc-3.12.2 depends on rdoc (~> 3.10, development)
railties-3.2.14 depends on rdoc (~> 3.4)
kaminari-0.14.1 depends on rdoc (>= 0, development)
arel-3.0.2 depends on rdoc (~> 3.10, development)
nokogiri-1.6.0 depends on rdoc (~> 3.10, development)
launchy-2.3.0 depends on rdoc (~> 3.12, development)
oauth2-0.8.1 depends on rdoc (>= 0, development)
sqlite3-1.3.7 depends on rdoc (~> 3.10, development)
uglifier-2.1.1 depends on rdoc (>= 3.11, development)
我的猜测是，当 gem 生成 ri 文档时，它使用的是rdoc 4.0.0，但随后使用3.12.2来尝试阅读它。在我的 Rails 项目上下文之外访问文档没有问题。
有什么建议么？我猜这可能不再是Rails 4中的问题，但目前这不是一个真正的选择。
非常感谢！
