My turn to put in a few notes on what I did to get Rails to work nice with my newly updated Mac OS: Snow Leopard. I got most of my information from Riding Rails blog post here: http://weblog.rubyonrails.org/2009/8/30/upgrading-to-snow-leopard. I would recommend reading that through, but I found a few new things along the way:
- Save your .bash_profile and your paths before doing the upgrade to Snow Leopard, you'll need them later.
- Backup your databases, and be ready to reload them in after this is all done since we need to reinstall mysql with the 64 bit version
- DO NOT use the latest mysql gem 2.8.x, it doesn't work. Use the 2.7 version instead like this:
- sudo env ARCHFLAGS="-arch x86_64" gem install mysql --version 2.7 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
- You must reinstall MacPorts before running the port commands listed in the blog post, you can now grab the latest Snow Leopard binary package here
- You will have to upgrade --force install with your MacPorts to get the libraries updated correctly. Takes a long time! If any fail, just try deactivating the failed one first, then uninstalling it with -f, then reinstalling it. If it's good, you will need to restart the upgrade --force install once more. This will help resolve the issues there.
- Use the script they have at the bottom of the post to see which gems you want to reinstall
After a lengthy MacPorts update, reinstalling gems, figuring out that I need the mysql 2.7 gem, getting git and some other paths like mysql back into my environment, everything fired right back up. Now I have to reload my databases and I should be good to go.
Hope you guys get your stuff working! If anything, read the comment thread on the Riding Rails blog, that'll help a ton!
