Updating Ruby Gems in Leopard

Published: 05 Dec 2007

This may be old news but I think little tidbits like this are important to document. If you're running Ruby on Leopard (Mac OS) and you're running into issues with your gems, try the following:

For intel-based macs:

sudo su
[Enter your password]
bash
export ARCHFLAGS="-arch i386"
gem update

For ppc macs:

sudo su
[Enter your password]
bash
export ARCHFLAGS="-arch ppc"
gem update
