I'm new to Ruby and I'm just trying to run a script. Firstly, when I try to bundle install it says:
Daniels-Air:Documents Daniel$ bundle install

Rubygems 2.0.3 is not threadsafe, so your gems will be installed one at a time. Upgrade to Rubygems 2.1.0 or higher to enable parallel gem installation.

An error occurred while installing ffi (1.9.10), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.9.10'` succeeds before bundling.
When I then try to execute the file anyway I come across the problem:
Could not find gem 'faraday' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.
Where do I get this 'faraday' gem from? Should it have come with the code I am trying to run, or should I update something? Sorry if I got some terminology wrong, I'm very new to Ruby.
