I downloaded you code and the app works fine. I can't get tests to run because of a different error than you are getting. Can't do more for you I'm afraid. You should reinstall the VM and start from scratch or download Jason's app and use it as you starting code.

What system are you working on? Did you use the virtual machine?Did you install the whole Ruby and Rails environment successfully? Can you upload your code to github so that we could take a look?

Maceij -- I'm using the virtual machine right now and looking at my todo_list rails app. I accidentally installed something called nokogiri when setting up though

OK, can you try and reinstall the virtual machine? I never managed to find a good answer for nokogiri problems and I never tried using the treehouse virtual machines. I think it wasn't your fault, capybara seems to be dependent on nokogiri somehow.

I'm not sure, uninstall and go through the process again according to videos ;)

I am getting the exact same thing and I have followed the videos exactly from the start. I am guessing that something had been changed somewhere along the way of the download path and these videos. The videos are over 2 years old and the version of Ruby I installed does not match theirs.

Bummer :(

I know this is an old post, but isn't the stack trace saying there's (ultimately) a problem with nokogiri?

If you ever come back to this, and you're on a linux/osx machine you could try:

apt-get install nokogiri

might just do the trick.
