From: "William C." Date: 2010-12-08T10:54:34+09:00 Subject: Error installing all gems on Windows Vista Ok, I've run into an issue running the gem install command on Windows Vista. Doesn't matter which gem I install (sqllite, rails, rspec,...) I get the same error. I can't figure out how to pass a debug switch to gem to get more info and the error message is rather vague. Suggestions?
