No such file to load -- ubygems (LoadError)

Whatever Ruby module I want to install under Cygwin I always get the same
error: ruby: No such file to load -- ubygems (LoadError)
I've tried install rubygem, rubyfcgi etc. After "ruby config.rb config" or
"ruby config.rb install" I get error: "ruby: No such file to load --
ubygems (LoadError)" It looks strange. I am using last cygwin installation
with ruby 1.8.2 ()ruby 1.8.2 (2004-12-25) [i386-cygwin])

True. Try to unset the RUBYOPT environment variable. Did the trick for me.

This tells ruby to put ubygems.rb under ~/local/rubygems.

This puts ubygems.rb under ~/local/rubygems.

ubygems.rb is not in your $LOAD_PATH for ruby.

You probably want to add:

export RUBYLIB=${HOME}/local/rubygems

This is how rubygems is typically installed (by not supplying the --
codefix option in step 4). But you do not have root access. You just
needed to add rubygems to the $LOAD_PATH.
