From: johnny mo Date: 2012-11-20T18:23:55+09:00 Subject: Re: some gems not working anymore This is Ubuntu 10.04. What happened was that I installed ruby 1.8.7 a long time ago. After a few months I installed rvm (which was previously missing) and ruby 1.9.3 and subsequently removed 1.8.7. That's why /usr/bin/gem exists. I've now removed it. No change to the situation though. -- Posted via http://www.ruby-forum.com/.
