You seem to be using Windows, which is never a good idea with Rails development (I know, Treehouse doesn't say it anywhere, but you have to trust me). I have no idea what this error means and it will be hard to find anyone who does, since almost all Rails devs use Unix-based systems. The only thing I can suggest is installing Linux (dual boot or using free VMWare Player) and using it for Rails development from now on. Less problems and more help online.

Oh, you can also try one of these online development environments:

Macieju,

Dzięki wielkie za support :)

Thank You very much for your support and guidance. I will take a look at your solutions, the seem to look very promising. I am a Ruby newbie (sounds nice, doesn't it?) and I didn't know that DOS platform will cause this much of a trouble.

Cheers!

In case of problems don't hesitate to ask on this forum. If you decide to go with Ubuntu on dual boot or virtual machine, make sure you follow this tutorial: https://gorails.com/setup/ubuntu/14.04 (choose "Using rvm" tab, not rbenv). You can skip the installation of databases for now.
