I now have - thanks to the help of many readers of this mailing list - installed Ruby 1.8.5 and gem 0.9.3 for both Cygwin and Windows. Under Cygwin, however, ruby doesn’t seem to make use of the installed gems: ~/tmp $ ruby -rubygem t2.rb ruby: no such file to load – ubygem (LoadError) Under pure Windows, it works fine. Any idea why this happens? Note that under Cygwin, I use the Ruby version which I can load via the Cygwin setup program. Ronald ---

I had that problem too. I don’t quite remember how I fixed it, but I think I found this page: [http://blog.labnotes.org/2005/11/06/setting-up-ruby-gems-on-cygwin/](http://blog.labnotes.org/2005/11/06/setting-up-ruby-gems-on-cygwin/) He says that he experienced the problem, and he thinks it’s because he had both the one-click installer and cygwin (I have this same setup at work – both one-click installer and cygwin). He didn’t dig too much into it, though, he just installed rubygems manually. I think this is what I did, too, but I’m not sure. To install rubygems without a working rubygem setup: - Follow the link on his blog to rubygems - Download the latest tarball (.tar.gz) - Unpack the tarball using cygwin or 7-zip - Run “ruby setup.rb install” inside the directory I think it’s a pure ruby package (no C code) so you shouldn’t need anything extra to install it. Once you’ve installed it, you should hopefully be able to use gems. Ben ---

I looked and I found “ubygems.rb” in /usr/lib/ruby/site\_ruby/1.8/. Interesting. That is a bit of a trick. Most people will probably want to do what I did and install rubygems from the tarball, though, since pretty much all ruby users use gems. I’m not sure whether rubygems is missing or if it doesn’t have the normal configuration when cygwin is first installed with the ruby package, but either way, it’s not the ideal configuration for most ruby users, and it can be fixed by unpacking the tarball and installing rubygems.

The O.-Click installer sets the environment variable RUBYOPT to the value “rubygems” to automatically require the the RubyGems package (this is a bit of a trick since the “r” is the require option, and the file being required is named “ubygems.rb”. Anyway, if you get rid of the RUBYOPT variable it should fix your problem. Curt
