一无所知....尝试ri String#upcase Ruby时 [英] Nothing known about.... when trying ri String#upcase Ruby

问题描述

我刚刚安装了RVM，并且正在阅读The Well-Grounded Rubyist一书.在第一章中，我应该尝试ri String#upcase来查看有关upcase方法的文档，但是会收到一条消息，提示:

I have just installed the RVM and I am reading The Well-Grounded Rubyist book. In the first chapter I am supposed to try ri String#upcase to view documentation on the upcase method, however I get a message saying:

对String#upcase一无所知

Nothing known about String#upcase

我在SO上找到了一些帖子，告诉我这可能是因为未安装RDoc.但是我不知道如何解决它.

I found some posts here on SO telling me that it probably is because RDoc is not installed. However I do not understand how to fix it.

我正在使用Mac OSX 10.6和最新的RVM.除了Apple开发人员工具包随附的标准Ruby解释器之外，我仅安装了1.9.2.

I am using Mac OSX 10.6, and latest RVM. I have only installed 1.9.2, in addition to the standard Ruby interpreter which come along with the Developer kit from Apple.
