Hi,

Am using ruby 1.9.3p194 and rubygems-2.1.7 on Ubuntu 12.0.

Getting the below error when trying to install Rails using rubyGems.

There is not a Ubuntu 12.0. Perhaps you mean 12.04. I recommend
using rvm to install and manage RoR. https://rvm.io/

Others suggest rbenv but I have no experience of that.

Is --include-dependencies a valid flag?

I don't see it when I call

gem help install

from the command line

 

Any sort of help is much appreciated.
