I'm quite new to ruby and I'm trying to view Ruby documentation through command prompt (I'm on Windows 7, Ruby version 2.0.0p195). However, no matter which command I try, for example ri String#upcase, I always get the message "Nothing known about..."

I have read several posts here but nothing seems to fix the problem.

With RVM in order to get the system documentation, you can issue the command

rvm docs generate-all

If you only want the ri documentation, this is what I do:

rvm docs generate-ri

  • All for the want of a full width highlighting? :) I guess it does communicate the `carriage-return` at the end of those commands. – vgoff Dec 13 '14 at 18:35
