我安装了Rails 3.2.8，gem更新--system说是最新的ruby gems，在Mac上运行ruby 1.9.3-p194。
当我这样做时
gem rdoc railties --ri --overwrite
我收到过多的警告。 （ - overwrite没有区别）。我发现各种各样的人抱怨但没有解决方案。
通过排序-u传递错误，唯一的行是：

“ick”是“ri Rails :: Engine”产生没有输出，实际上它有很多非常漂亮的文档。我经常在我的Mac上碰到这个问题，并想在我的Mac上运行一整套文档。
命令
可能是一个单独的问题gem rdoc bigdecimal --ri
产生相同的警告，但以：
结束ERROR: While executing gem ... (Errno::ENOENT)
No such file or directory - /usr/local/prvm/ruby-1.9.3-p194/lib/ruby/gems/1.9.1/gems/bigdecimal-1.1.0
这是铁路还是rubygems或我当地设置的问题？
有什么方法可以解决它吗？
答案 0 :(得分：0)
如果出现错误，RubyGems将明确说出并以非零错误代码退出。对于第一种情况，正如您所注意到的，您只会看到警告。
这些警告已在RubyGems中得到修复，但将修复程序反向移植到RubyGems 1.8并不容易。
对于第二种情况，我们的目标是使用Ruby 2.0中的“默认gems”功能来解决这个问题。 bigdecimal文档作为ruby的一部分提供，因此无需重新生成它。
答案 1 :(得分：0)
问题非常糟糕。我错误地将警告与“gem rdoc railties”没有产生内部文档的事实相关联。我终于找到了那个特定的问题。出于某种原因，gem规范排除了所有文件。只需删除该行，即可获得良好的文档。
