Rails Server won't start after Ruby upgrade - Segmentation Fault -


after upgrading ruby 1.9.3-p429, tried start rails server. told me rails not installed so, boldly did 'gem install rails'. when try start server, i'm getting this:

andrunix@amp-laptop~/code/madrilla$ rails s /users/andrunix/.rvm/gems/ruby-1.9.3-p429/gems/mysql2-0.3.11/lib/mysql2/mysql2.bundle: [bug] segmentation fault ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]  abort trap: 6

i have no idea why says, "ruby 1.8.7" in output. perhaps that's clue problem.

but anyway, super frustrated @ point.

and way, on os x.

help me please!

try set version you've installed default whole system:

rvm --default use  ruby-1.9.3-p429
