This is what I call (ruby one-click-installer on Windows):

1. In my path there is an entry for c:\ruby\bin
2. In my ruby\bin directory, there is a file called gem.bat (this one is
started by windows if you type gem)

3. This gem file contains one beautiful line
"c:\ruby\bin\ruby.exe" "c:\ruby\bin\gem" %1 %2 %3 %4 %5 %6 %7 %8 %9

So my guess is, make sure you have the gem ruby file installed (get it
from rubyforge? I doesn't exactly know where to download gem as I use
the one-click-stuff) and create this batch file.

HTH,

http://docs.rubygems.org/read... should help with RubyGems.

Boy, that was easy.Any clues about rdoc and ri?Still no worky.I wonder if documentation is really nessisary though? Sure its nice, butis there any difference between having it local and viewing it on ruby-doc ?I guess the difference would be if I ever needed to write my own documentation.--Alex Combashttp://noodlejunkie.blo...

Well, the online version is faster than ri ;)

But at least a working rdoc is somewhat important, I'd say.

Well, I have a crappy CPU, and a wonderful cable connection.

And unless you set that wossname header to no-cache globally, the strain can't

I meant for documentation generation actually.
