I'm a newbie as far as Ruby goes, and I want to install rubygems in
Cygwin. I have Ruby installed, but I don't know what I need to install
gems. This message shows that it can't find, or I don't have the files
needed:
$ gem install -r net-ssh
/cygdrive/c/ruby/bin/gem:9:in `require': no such file to load --
rubygems (LoadE
rror)
from /cygdrive/c/ruby/bin/gem:9
Can anyone tell me what I need to download, and where I can it?
Thanks in advance....

I don't use Cygwin (or windows), so my instructions may be inaccurate. gem is
a command provided by rubygems, so you can't use it to install rubygems
itself. To do this, instead, you should go to the rubygems project page on
rubyforge (http://rubyforge.org/projects/rubygems/\) and download it. After
following the 'download' link, you'll be able to choose between a gzip and a
zip file (the other file, rubygems-update-0.9.4.gem can only be used if you
already have rubygems installed). After downloading the file, uncompress it,
cd into the directory you just created and issue the command

I think you need to change the path where rubygems searches for libraries. You obviously have the "gem" executable, but gem is running "require 'rubygems'", which is failing. You should find rubygems.rb and note its folder. Say it's in /cygdrive/c/ruby/lib/, for example. You can start ruby with that information: ruby -I /cygdrive/c/ruby/lib/. It is up to you whether to type that manually each time you need to (i.e., ruby -I /cygdrive/c/ruby/lib/ /cygdrive/c/ruby/bin/gem install -r something), or write a wrapper script that calls the ruby executable with that argument. The second solution will work for any invocation of ruby, while you can obviously only utilize the first solution if ruby starts because you typed "ruby" on the command line (might as well use an alias, if that's the case).
But it seems like this shouldn't be a problem... are there any better ways to install ruby on cygwin? (I haven't used cygwin in years...)
Stefano,
I tried your directions and everything now works thank you very much!
Thanks also to everyone who responded. Hopefully I'll be able to help
you all out someday.
