Ruby on rails Ruby文档更新错误

我已经在MacPorts上安装了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

规格

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上运行已经是一段相当漫长的旅程。在接下来的教程中，我决定安装/更新Rails API文档，并遇到了以下错误：

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

当我执行

gemserver

时，服务器启动了。所以我可能在一年前安装了docs，然后完全忘记了它

我能做些什么来消除所有这些错误？或者我可以安全地忽略它们并继续吗？

您可以安全地忽略这些错误

现在，您可以通过指定

gem install rails--no ri--no rdoc

来安装gems，以安装rails而不出现这些错误

将来，您可以添加：

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

到您的

~/.gemrc

文件，全局忽略将来安装gem的文档

---

另外，如果您刚刚开始，我建议您使用ruby版本管理器，如或。在管理不同的ruby版本和Gemset时，它让生活变得更加轻松。

我在

Debian

linux上得到了相同的警告，我正在使用

rvm

和

ruby-1.9.3-p194

我通过改变第127行来消除大部分错误

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

127添加规范gempec if gempec

至

127 Gem:：Specification。添加规范gempec if gempec

至于其他人，他们说他们不赞成，没有替代品

我之所以找到这条线索，是因为我想了解更多关于这些的信息。 有人认为有更新吗？ 警告说明这些将在

2011-11-01

当天或之后删除。

时间已经过去。

如果您的rdoc版本<3.0，请尝试

gem安装rdoc

或

gem更新rdoc

---

RDoc从Ruby源文件生成文档。因此，正如@marksands所说的，让代码运行并不是绝对必要的，它可以很好地解决错误的根源

感谢@Mark Sands的输入！你是第二个推荐RVM的人。我会调查的。我也意识到我很久以前买的书RailsSpace有很多过时的代码。没问题！请务必阅读rvm和rbenv的优缺点，以形成您自己对使用哪个版本管理器的看法。
