ruby 1.9 ri on Windows knows nothing about any classes

Question

I'm using Windows XP SP2, and installed Ruby through Ruby 1.9 one click installer. Then when I try to using ri, I get the following response, can anyone help me with my problem? ``` C:\Documents and Settings\eyang>ruby --version ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32] C:\Documents and Settings\eyang>ri --version ri 2.2.2 C:\Documents and Settings\eyang>ri String Updating class cache with 0 classes... Nothing known about String C:\Documents and Settings\eyang>ri Updating class cache with 0 classes... No ri data found If you've installed Ruby yourself, you need to generate documentation using: make install-doc from the same place you ran `make` to build ruby. If you installed Ruby from a packaging system, then you may need to install an additional package, or ask the packager to enable ri generation. C:\Documents and Settings\eyang> ``` By the way, when I try to use gem, I got the following error messages too, anyone can explain it? ``` C:\Documents and Settings\eyang>…

Accepted Answer

RubyInstaller do not bundle RI documentation, as it increased the size of the distribution and the time to install the package.

Instead, we bundled CHM (Windows Help) files for both Core and StdLib API.

This was discussed in the RubyInstaller group and the decision was made on that base.

As for your other point, two things: you need to provide a gem name or part of it, since there are 12K gems in RubyForge.

Also, depending on your console configuration (Latin or something) the Not Enough space error will be related to the terminal itself, not RubyGems.
