19 Nov 2007 Tiger + Rails + Leopard = Ouch
After having gone through the pain of installing Ruby on Rails on my MacBook Pro running Tiger (OS X 10.4) I was pleased to see that Leopard (OS X 10.5) ships with Rails ‘pre-installed’ and ready to go.
So, after I upgraded my installation on Friday night I was perplexed when trying to run my Rails apps. Why was it broken?
In the end, it turns out there were several problems.
Firstly, I figured that since I had a ‘fresh’ Ruby and Rails that my gems were missing. A quick ‘gem install’ failed with messages about Ruby headers. A Google search told me that I needed to install XCode to get the Ruby headers. Really? OK, so I did that.
Second, it appears that the MySQL connector was broken and needed to be installed. Worse, it is a pretty cryptic command required:
sudo env ARCHFLAGS="-arch i386" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Third, I was getting the usual error when MySQL is not running and after some investigation it turned out the MySQL was an application that didn’t make the migration. A quick install, database creation and ‘rake migrate’ and I was back in business.
Certainly far from a pain free migration, plus I am glad that I didn’t have any critical data in MySQL 🙂
