Required Ruby,Git freelancer for Help setting up console/git with Jeykll site job

Help me connect to our Jeykll site's github via the console.

Console is pushing an error

' There was an error evaluating `Gemfile`: This Gemfile contains multiple primary sources. Each source after the first must include a block to indicate which gems should come from that source. Bundler cannot continue.'

but I am using the same gemfile as others.

Job will also include getting localhost up and running.

This is a one time job, but if done well with fast response time there will probably be more work at a later date.
