Just updated to gem 1.3.0 on XP. > gem -v 1.3.0 > gem list ERROR: while executing gem ... undefined method 'uid' for nil::NilClass Any ideas on this? If I wanted to try an earlier version of gem instead, how do I revert exactly? I find the whole process of using gem-update gem files a bit confusing when it comes to a question like this.
