When trying to run jekyll serve, it seems to build correctly (though with warnings that I haven't been able to resolve), but then fails to serve. jekyll build completes, but the resulting files are missing the compiled CSS.
Output from jekyll serve:

When trying to start a Jekyll project, I did have to create a link of Ruby versions because it was looking for 'Ruby2.1', but I'm not sure if this is playing a role in the current problem: ln -s /usr/bin/ruby '/usr/bin/ruby2.1'.
According to my package manager, I've installed Ruby 2.3.0. But according to which ruby, I'm using 2.0.0 which it's getting from rvm: /home/xxxxxxx/.rvm/rubies/ruby-2.0.0-p643/bin/ruby. And as I mentioned before, Jekyll seems to want v2.1 for something. I'm guessing these conflicting versions are somehow causing the problem, but I don't know how to resolve it.

In my case I had to install the ffi library with gem:
gem install ffi
This error is probably caused by an older version of the library installed in the system. gem then installs the correct version for your project.

The problem for me seemed to be rvm (which I'm not sure how I ended up using). The solution was to remove rvm with rvm implode, then reinstall jekyll with gem install jekyll. Both the warnings and errors disappeared, and it is serving properly.
