A simple reinstall of rubygems and the gems is all that was needed to restore the state. (I was trying to avoid this being lazy). RI is happy again, gems are being found with no issue. -- Kind Regards, Rajinder Yadav http://DevMentor.org Do Good! - Share Freely

I bet if you do 'sudo apt-get remove rubygems' (I think that's right) you'll see what I mean. This Debian distro of rubygems won't work with the source distro of Ruby (at least not easily). You'll need to remove the one installed through apt and install from source as mentioned above.

Note that this is not the gem binary, but rather the file which allows your program to load gems. The ... stands in for an installation path which varies from system to system. But should be something like /usr or /usr/local on a Debian based system. Actually self installed stuff should be in /user/local IIRC so as not to collide with packaged stuff. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale |
