Failed to install a gem

Question

I'm running Ubuntu 13.04, and I'm trying to use this project.

I understand that I first need to install its dependencies, but when I try to install the Grape gem I'm getting this error

ERROR:  Error installing grape:
ERROR: Failed to build gem native extension.

    /usr/bin/ruby1.9.1 extconf.rb
    /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from extconf.rb:13:in `<main>'

I pretty new to Ruby at all, so I'll appreciate any help

Thanks

It looks like you might have to use ruby 1.9.3 with that project, as it lists it it's gemfile. Are you using a ruby version manager? — nil, Mar 04 '14 at 20:23
Well you're really going to have to learn what that is and you're going to need to use it. — nil, Mar 04 '14 at 20:37
Try running `sudo apt-get install ruby2.0-dev` and retry installing gem — BroiSatse, Mar 04 '14 at 20:48
Alright, so I installed ruby 1.9.1 and now it's working fine. Thanks — orelzion, Mar 04 '14 at 21:17
I highly recommend using https://rvm.io/ or http://www.rubyinside.com/rbenv-a-simple-new-ruby-version-management-tool-5302.html to manage your ruby versions and ruby gems. — grenierm5, Mar 04 '14 at 21:50
