This was the one post I made on my tumblr blog. Since it looked kind of lonely up there I thought I would bring it over…
I had quite a bit of a headache trying to get the MySQL ruby gem working on Snow Leopard. Every time I would try to migrate my database or start Mongrel I would get “NameError (uninitialized constant MysqlCompat::MysqlRes)”.
After doing some googling I found the ruby weblog guide for upgrading to Snow Leopard. There they recommend installing the 64 bit version of MySQL and then to install the gem run the following command:
MySQL and the gem installed ok but I would still get the same error when trying to migrate or start the development server. A little more googling led me to Robby Grossman’s blog with instructions for installing MySQL using macports and a slightly different command for installing the gem. To install MySQL with macports:
Then I combined his instructions for installing the gem with the one on the ruby weblog.
Hope this helps, Good luck!
