Category: `gem install` command Group: v1.3.x >Status: Closed Resolution: None Priority: 3 Submitted By: Dr Nic Williams (nicwilliams) Assigned to: Nobody (None) Summary: undefined method `prerelease?' for nil:NilClass Initial Comment: In both ruby18 and ruby19, rubygems 1.3.5 gives off "undefined method `prerelease?' for nil:NilClass" errors a lot. I can't isolate exactly what is causing it. How do I rollback to an old rubygems version? ---------------------------------------------------------------------- Comment By: Dr Nic Williams (nicwilliams) Date: 2009-08-17 23:28 Message: Ah, it turns out it was another gem source that caused the issues. I removed it and "gem install rails" + merb works. Thanks. ---------------------------------------------------------------------- Comment By: Luis Lavena (luislavena) Date: 2009-08-17 23:15 Message: Sounds more like a corrupt index than a bug in the gem dependencies. Did you have by change github as a source repository? There are a couple of bugs over there that are making gem installation a real pain. Please try: sudo gem install rails --debug -V ---------------------------------------------------------------------- Comment By: Dr Nic Williams (nicwilliams) Date: 2009-08-17 23:13 Message: I think the bug is related to gems with dependencies: ~$ sudo gem install rails Password: ERROR: While executing gem ... (NoMethodError) undefined method `prerelease?' for nil:NilClass ~$ sudo gem install activerecord ERROR: While executing gem ... (NoMethodError) undefined method `prerelease?' for nil:NilClass ~$ sudo gem install activesupport Successfully installed activesupport-2.3.3 1 gem installed ---------------------------------------------------------------------- Comment By: Chad Woolley (thewoolleyman) Date: 2009-08-17 23:08 Message: You can rollback by running setup.rb from an old version - it has worked for me. ---------------------------------------------------------------------- Comment By: Dr Nic Williams (nicwilliams) Date: 2009-08-17 20:35 Message: An example of the bug vs no bug: gem install merb - causes the bug gem install merb-core - no bug ---------------------------------------------------------------------- You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=575&aid=26936&group_id=126 _______________________________________________ Rubygems-developers mailing list http://rubyforge.org/projects/rubygems Rubygems-developers@rubyforge.org http://rubyforge.org/mailman/listinfo/rubygems-developers
