RadRails – Unable to detect ruby install on OS X Leopard

I installed the RadRails plugin for Eclipse and Aptana today.
On first start, it complains that it is “Unable to detect ruby install” on my Leopard macbook.

Now, I know ruby is installed and working so had to try and figure out the path to the ruby installation.

Took me a while to work it out, I thought it would be under /usr/.. but it’s actually here:


After adding a new RubyVM with this path everything was good again.

Incidentally, although Aptana is available on it’s own as an IDE (built with the Eclipse framework), I decided to use it as a plugin for a native Eclipse IDE. That way I just have one IDE for Java, C++ as well as RoR. Made sense to me.

I’ve only had a quick play with it but it already beats the bejesus out of my Notepad and command line setup on XP. đŸ™‚

    No problems, I was actually going to have a look this evening to add a bug report in (or see if it had been reported already).
