I feel your pain. I abandoned Rails cause I couldn't get it up and running.

Looks like you don't have XCode Command Line Tools. Check this article

Ilya, you had my attention there for a sec, cause I really wanted to do rails. It looks like Xcode command line is just for mac?

Yep, this is for Mac :) Are you on Windows or Linux?

Windows sadly. I tried ubuntu (user friendly linux) it just didn't click w/me. And to get a decent mac is out of my price range.

What does it mean "Didn't click"? :) Did you install it but you don't like it? It's OK, there are some many Linux distros. My personal choice is Fedora for workstation and CentOS for deployment.

But if you serious about becoming a Rails developer I highly recommend you to use Linux as your development OS. It will prevent you from some weird things and also being confident with Linux and CLI it's a "must have" skill for future Rails ninja. You will love it, I promise :)

There are 2 ways to use it in your case:

  1. Install it as a second system to your PC. You can google many detailed guides about that. I'm sure it'll be easy for you.

  2. Use Linux as a virtual machine.

    • with graphical interface - take a look to VirtualBox or some analogues. But I'm not sure you really need GUI for you VM. 99% of work is CLI-base.
    • CLI-mode (Recommended option) Here Vagrant or Docker(or both) come in to play. I do recommend to start with Vagrant, just follow the Getting Started section in docs. And the great benefit for using Vagrant is to add one more skill to your toolbelt.

Hope it will be helpful. Good luck :)

john larson , if you want to give it one more go, we've created a new video for installing Rails 5 on Windows that might help you. If that works, you'll be all set to try Rails 5 Basics!
