我已经安装了 MacPorts 的 Ruby on Rails，从昨天开始我一直在更新和修改它，因为我想重新学习这门语言。

眼镜

ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [i686-darwin10]
rails -v
Rails 3.0.3
gem -v
1.8.5

旅程

到目前为止，让 Ruby、Rails 和 Gems 在我的 Mac 上运行是一段相当长的旅程。在遵循教程后，我决定安装/更新 Rails API 文档，但遇到了以下错误：

Installing ri documentation for activesupport-3.2.3...

unrecognized option `--encoding'

For help on options, try 'rdoc --help'

ERROR:  While generating documentation for activesupport-3.2.3
... MESSAGE:   exit
... RDOC args: --ri --op /opt/local/lib/ruby/gems/1.8/doc/activesupport-3.2.3/ri --encoding UTF-8 lib --title activesupport-3.2.3 Documentation --quiet

当我这样做时gem server，服务器已启动。所以我可能在一年前安装了文档并且完全忘记了它。

我该怎么做才能摆脱所有这些错误？或者我可以安全地忽略它们并继续前进吗？

您可以放心地忽略这些错误。

gem install rails --no-ri --no-rdoc现在，您可以通过指定安装 Rails来安装 gems而不会出现这些错误。

将来，您可以添加：

gem: --no-ri --no-rdoc

到您的~/.gemrc文件中，以全局忽略未来 gem 安装的文档。

此外，如果您刚刚开始，我建议您使用 ruby​​ 版本管理器，例如rvm或rbenv。在管理不同的 ruby​​ 版本和 gemset 时，它让生活变得如此轻松。

尝试gem install rdoc或者 gem update rdoc如果您的 rdoc 版本 < 3.0。

RDoc 从 Ruby 源文件生成文档。因此，正如@Mark Sands 所说，让您的代码运行并不是绝对必要的，拥有并解决错误的根源可能会很好。

我在 linux 上得到了同样的警告Debian，我正在使用rvmwith ruby-1.9.3-p194。

我通过更改第 127 行消除了它们中的大部分

~/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/source_index.rb

127 add_spec gemspec if gemspec到127 Gem::Specification.add_spec gemspec if gemspec

至于其他人，他们说已弃用，没有替代品。

我只发现了这个线程，因为我想了解更多关于这些的信息。有人认为有更新吗？警告声明这些将在 或之后被删除2011-11-01。时间已经过去了。
