Further investigations and “hacking” about has revealed that its not the OS that’s the issue.

RoR does not support MySQL x64

I installed x86 and it ran first time.

Keep them RoR posts coming! Looking forward to the next one, as this one already saved me hours of pain!

I would try uninstalling the whole Ruby stack (leave MySQL installed) and make sure there’s no trace of mysql gems.

Are you running x86 or x64 development machines? I have been having issues as described in this post and have tried your solution.

I am now getting the following error which I believe is to do with it trying to install x86 drivers on x64.

I then fire up WebRick and get:

Did you run into any of these issues?
