What did you run before this problem occurs? gem install eventmachine --platform=win32?

I've found the same problem with eventmachine. Tell me if it helps.

You were correct... however their guide didn't help. A quick googling about and I discovered that steps:

1.) gem install eventmachine-win32

Enabled the install to work... (instead of "gem install eventmachine --platform=win32"), then continuing on with your original suggest:-

2). gem install win32-changenotify win32-event livereload

Complete the install. Now to try it :) Thanks for your help - much appreciated & happy ny to you!

I just installed livereload on a Windows XP virtual machine. I had the same error. gem install eventmachine-win32 works well. Thanks!
