I am trying to run a rails server sample that I downloaded. But, I am getting a permissions error:
I run:
rails server
I get:
=> Booting Puma
=> Rails 4.2.4 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Exiting

Seeing that it was a permissions error I tried:
sudo rails server
But I only received this error
Your Ruby version is 1.9.3, but your Gemfile specified 2.1.7
How do I overcome the permissions problem when the root user seems to be using a different version of ruby?
EDIT 1:
ruby --version
returns:
ruby 2.1.7p400 (2015-08-18 revision 51632) [i686-linux]
EDIT 2:
sudo ruby --version
returns:
ruby 1.9.3p484 (2013-11-22 revision 43786) [i686-linux]
EDIT 3:
There is no tmp file in my web-app directory. When I type ls -la I get:

First one must create the tmp directory, then give it the necessary permissions. This can be done with the following code:
sudo mkdir tmp
sudo chmod 777 tmp
