ruby-on-rails - Ruby文档更新错误

Question

我已经在MacPorts上安装了Ruby on Rails，从昨天开始，我一直在进行更新和修改，因为我想重新学习这种语言。

规范

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上运行已经是一段漫长的旅程。在学习了教程之后，我决定安装/更新Rails API文档，并且遇到了这些错误:

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gem server时，服务器已启动。因此，我大概在一年前安装了文档，却完全忘记了。

我该怎么做才能摆脱所有这些错误？还是我可以安全地忽略它们并继续前进？

Answer 1

您可以放心地忽略这些错误。

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

将来，您可以添加:

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

到~/.gemrc文件中，以全局忽略以后安装gem的文档。

另外，如果您刚刚开始使用，我建议您使用ruby版本管理器，例如rvm或rbenv。当管理不同的 ruby 版本和 gem 集时，它使生活变得更加轻松。
