I've been getting back into Rails development again, and I've been trying to find the right IDE to work in. I'm an IntelliJ fan, and I hate Eclipse. But, last time I was using Rails I used RadRails, and it was ok. However, now IntelliJ 7 has support for Rails development, and I thought I'd try it out.
First thing I ran into when I was configuring my project is setting up the Ruby SDK. Much like a Java project needs to know where the JDK home directory lives Ruby projects need to know where Ruby SDK lives. Only problem is on a Mac or Linux box those aren't so simple to find. I also had rebuilt Ruby so I could get readline support and installed it under /usr/local.
I tried /usr/local/lib/ruby that didn't work. I tried /usr/local/lib/ruby/1.8 that didn't work. Finally after stumbling around without any success I tried /usr/local and viola it worked.
If you didn't rebuild Ruby and are using the default Mac install. It would be /usr. Make sense? No not at all, but hopefully this blog post will help some peeps in the future.
