My debugger is having a problem with rubygems v1.0.1. I would like to revert back to rubygems 0.9, if that is possible. What steps are necessary to back out v1.0.1 and re-install 0.9.x? Thanks for your time, dvn ---

The IDE debugger I am using is ArachnoRuby. I switched my development environment, where the new one has rubygems 1.0.1. However, in processing the gem and require statements, I would get this weird error about not being able to convert nil to integer. The exact same script would work with SCITE and from the command line. I contacted the author of ArachnoRuby and said it was odd. He said it made sense to him and there is something he needs to fix. I will update all my servers to rubygems 0.9.4. I wasn’t sure which version is the correct one. All my servers are using 0.9.0; and they are all fine. Anything more you need? Just let me know. Thanks a bunch, dvn ---

The cleanest method will involve: Download rubygems-0.9.0.zip package from rubyforge: [http://rubyforge.org/frs/shownotes.php?release\_id=5803](http://rubyforge.org/frs/shownotes.php?release_id=5803) Unzip and run ‘ruby setup.rb install’ Just curious: why you want to revert to 0.9.0? instead of 0.9.4 which was more stable. Also, can you provide more information about the trouble you’re having, so we can track if the problem is in RubyGems or the “debugger” gem you mention. Regards, ---
