It doesn't look like you have rubygems installed, which is the remit of devkit

There is a good tutorial here

I think your error is because you're using gems in command line. Try using gem -v and you'll see that it will work. If you use the singular gem , you can then fire gem install rails , to get it so you're able to install rails directly
